How to Make Bone Broth Why Bison Bones Change Everything
Bone broth is made by simmering collagen-rich bones — knuckles, feet, neck bones, marrow bones — in water with an acid component (apple cider vinegar is standard) at 170-190°F for 12-24 hours for beef and bison, 4-6 hours for poultry. The collagen (primarily Type I and Type III) in the bone and connective tissue hydrolyzes slowly into gelatin under sustained heat — the source of the broth's body, mouthfeel, and the glycine content that makes bone broth nutritionally distinct from meat stock. Beck & Bulow Bison Broth Bones from the Bison Meat catalog produce a denser, darker, more mineral-rich broth than conventional feedlot beef bones because pasture-raised bison have higher bone density from weight-bearing activity on open range — more mineral packed into each gram of cortical bone. The three most common bone broth mistakes: full boiling (destroys gelatin proteins), no acid (inhibits mineral extraction), and insufficient time (collagen hydrolysis requires sustained heat — the gelatin test tells you when it is done). This guide covers all three and everything that follows.
The Difference Between Stock and Bone Broth — and Why It Matters
Most people use the words stock and bone broth interchangeably. They are not the same thing. The distinction is not semantic — it is chemical, and the difference in the end product is significant enough that the two preparations serve different purposes in the kitchen and deliver different nutritional profiles.
Stock is the culinary foundation — bones simmered for 4-8 hours to extract collagen, flavor, and body. It is the base for sauces, braises, and soups. Bone broth is the same process extended — 12-24 hours for beef and bison bones — to the point where the collagen hydrolysis is essentially complete and the resulting liquid is gelatin-dense, mineral-rich, and glycine-loaded in a way that a 4-hour stock is not. The gelatin sets the broth to a firm jelly when refrigerated. The minerals extracted by the acid component are bioavailable calcium, phosphorus, and magnesium from the bone matrix. The glycine — the most abundant amino acid in collagen — is the specific compound that gives bone broth its claimed health benefits.
And then there is the sourcing question. A Beck & Bulow Bison Broth Bones batch is not the same as a bag of conventional feedlot beef bones from the grocery store, and the difference shows up in the finished broth. This article covers why — the bone density argument, the collagen hydrolysis science, the full protocol, and the gelatin test that tells you when you have made actual bone broth rather than thin stock.
"The gelatin test does not lie. If the broth does not set to a firm jelly in the refrigerator, the collagen hydrolysis was incomplete. More time, more acid, or better bones. Usually all three."
1. The Science: What Bone Broth Actually Is and How It Forms
Collagen and Its Conversion to Gelatin
Bone and connective tissue contain collagen — primarily Type I collagen (the dominant structural protein in bone, tendon, and skin) and Type III collagen (found in softer connective tissue and the periosteum layer of bone). Collagen is a triple helix protein structure — three protein chains wound around each other in a left-handed helix, giving the molecule extraordinary tensile strength. It is what makes tendons and ligaments nearly inextensible and what gives cartilage its compressive resistance.
When collagen is exposed to sustained heat in water, the hydrogen bonds stabilizing the triple helix begin to break — a process called hydrolysis. The three protein chains unwind and denature into gelatin — a disordered collection of single-chain proteins (alpha chains) that have lost the triple-helix structure but retained the amino acid composition of the original collagen. The Journal of Food Science (onlinelibrary.wiley.com/journal/17503841) documents the hydrolysis threshold at approximately 165-185°F — with 170-190°F being the practical target for bone broth. The process is time-dependent: a full 12-24 hours is required for complete collagen hydrolysis from dense cortical bone.
Glycine — The Amino Acid the Modern Diet Is Deficient In
Glycine makes up approximately 33% of collagen by amino acid composition — the most abundant amino acid in the collagen molecule (Journal of Agricultural and Food Chemistry, pubs.acs.org/jafc). When collagen hydrolyzes to gelatin in the broth, the resulting gelatin is loaded with glycine, proline, hydroxyproline, and alanine — amino acids that are abundant in connective tissue but scarce in the muscle meat that dominates the modern diet.
The glycine deficiency argument for bone broth is well-grounded: a diet composed primarily of muscle meat provides a protein source high in methionine (the primary sulfur amino acid in muscle) but low in glycine. The methionine-glycine balance matters because methionine metabolism produces homocysteine — a cardiovascular risk factor that glycine helps clear through the transsulfuration pathway. The ancestral diet that included nose-to-tail eating — bone broth, organ meats, connective tissue — was naturally glycine-sufficient. The modern muscle-meat-dominant diet is not. Bone broth is the most practical way to restore the balance.
Minerals From the Bone Matrix
Bone is approximately 70% mineral by dry weight — primarily calcium and phosphorus in the hydroxyapatite crystal structure, with smaller amounts of magnesium, potassium, and zinc. These minerals are locked in the crystalline matrix of the cortical bone and require an acidic environment to be released into the broth. Apple cider vinegar — with a pH of approximately 3-4 — disrupts the calcium-phosphate bonds in the hydroxyapatite crystal, releasing the minerals into solution during the simmer. The same mechanism works with any food-safe acid: lemon juice, white wine vinegar, or a splash of white wine.
An Interesting Historical Fact: Bone Broth Predates Cooking
Archaeological evidence for bone marrow extraction dates to at least 1.7 million years ago — predating any evidence of controlled fire use by several hundred thousand years. Homo erectus at sites in Olduvai Gorge, Tanzania and Boxgrove, England used stone tools to crack large animal bones specifically for the marrow — the most calorically dense and nutrient-rich component of any large game kill. The marrow extraction is the oldest form of what we now call nose-to-tail eating. The addition of water and heat to create broth came later — with controlled fire — but the foundational human understanding that the bones hold the most concentrated nutrition is among the oldest food behaviors in the human lineage. Every bowl of bone broth is a practice with a longer history than agriculture, writing, or civilization.
2. Why Bison Bones Produce a Different Result Than Conventional Beef Bones
The Bone Density Argument
Pasture-raised bison are physically active animals — they graze on open range, cover miles daily, and carry their body mass on weight-bearing skeletal structures that are under continuous load. The mechanical stress of daily locomotion on open pasture is the primary driver of bone remodeling — the continuous process by which osteoblasts deposit new bone matrix in response to mechanical loading. Active animals have denser bones. Denser bones contain more hydroxyapatite mineral per gram of cortical bone and more collagen per unit volume in the periosteal and endosteal layers.
The Journal of Animal Science (academic.oup.com/jas) documents higher bone mineral density in pasture-raised animals compared to confinement-raised equivalents — a direct consequence of the mechanical loading difference. A Beck & Bulow Bison Broth Bones package from a pasture-raised bison contains more mineral per gram of bone and more collagen than the equivalent weight of conventional feedlot beef bones — which means the finished broth carries more dissolved minerals and more gelatin after the same simmer time.
The Omega-3 Fat Contribution
Bison bone marrow — the fat-rich material in the central cavity of long bones — carries the same favorable omega-3 to omega-6 ratio as the rest of the pasture-raised bison. The marrow fat is released into the broth during the simmer, carrying the omega-3-derived flavor compounds and the specific fat-soluble nutrients of the pasture diet. The surface fat that accumulates at the top of a bison bone broth is a richer, more nutritionally complex fat than the equivalent from grain-finished cattle — and it can be skimmed and retained as a cooking fat similar to Bison Tallow for use in subsequent meals.
The Flavor Difference
The finished bison bone broth is darker, more deeply flavored, and more complex than conventional feedlot beef bone broth. The color comes from the higher myoglobin content of the pasture-raised bison's more active muscle tissue — residual myoglobin on the bone surfaces and in the marrow contributes to the broth's deep amber color. The flavor comes from the higher concentration of dissolved minerals, Maillard compounds from the roasted bone surfaces, and the specific flavor volatiles of the pasture diet fat. A batch of bison bone broth produced from Beck & Bulow Bison Broth Bones tastes distinctly different from grocery store beef bone broth — more mineral, more savory, and with a body that reflects the higher gelatin density.
3. The Complete Bison Bone Broth Protocol
Step 1 — Choose the Right Bones
The most collagen-rich bones are the ones with the most connective tissue attachment points and the greatest surface area of cartilage:
• Knuckle bones: The highest cartilage content per gram of any bone — the knuckle joint is a mass of cartilage and connective tissue that yields the most gelatin per hour of simmer. The primary driver of gelatin density in the finished broth.
• Marrow bones (femur, tibia): The richest source of bone marrow fat and fat-soluble nutrients. Less collagen per gram than knuckle bones but essential for the depth of flavor and the nutrient density of the marrow component.
• Ribs and short ribs: The Bison Short Ribs carry significant collagen in the periosteal and intercostal connective tissue. After a slow braise, the leftover bones are excellent additions to a subsequent broth batch.
• The Beck & Bulow Bison Broth Bones package: A mix of the above formats from the pasture-raised bison herd — selected specifically for collagen and marrow content to produce the densest possible gelatin yield from a single batch.
Step 2 — Roast the Bones First
This is the step most home cooks skip and the one that produces the biggest flavor difference. Roasting the bones before the broth simmer produces the Maillard reaction on the bone surfaces and marrow — creating hundreds of new flavor compounds that dissolve into the broth during the long simmer and produce the deep, complex, restaurant-quality flavor that unroasted bone broth lacks. However, you can still skip this step and make extremely nourishing and delicious bone broth.
• Temperature: 425-450°F
• Time: 30-40 minutes until deeply browned on all surfaces.
• Pan setup: Single layer on a rimmed sheet pan. The bones should not overlap — overlapping prevents browning and steams rather than roasts.
• The fond: After roasting, deglaze the roasting pan with a splash of cold water and add the fond (the browned drippings stuck to the pan) to the broth pot. The fond contains the most concentrated Maillard compounds from the roast and significantly amplifies the finished flavor.
Step 3 — The Acid Soak
Add the roasted bones to the pot and cover completely with cold water. Add 2 tablespoons of apple cider vinegar per pot of broth. Allow the bones to soak in the cold acidic water for 30-60 minutes before applying heat. This cold-soak period allows the vinegar to begin disrupting the hydroxyapatite mineral bonds before the heat is applied — maximizing mineral extraction during the subsequent simmer.
The vinegar flavor does not carry into the finished broth at this concentration. The acid is functional, not flavoring. Any food-safe acid works: white vinegar, lemon juice, a splash of dry white wine.
Step 4 — Bring to a Bare Simmer, Not a Boil
This is the most critical temperature decision in bone broth cookery. Do not boil. A full rolling boil violently agitates the proteins in the broth, causing them to emulsify and cloud — the gelatin proteins that should remain dissolved in solution get physically disrupted into a cloudy, less elegant broth with a slightly bitter, less clean flavor. A bare simmer at 170-190°F — where small bubbles occasionally break the surface but the broth is not churning — allows gentle, complete collagen hydrolysis without protein disruption.
The oven method: 250°F in a covered Dutch oven or roasting vessel overnight produces the ideal temperature — below boiling, above the hydrolysis threshold, completely unattended. The most practical method for a full 18-24 hour bison bone broth.
The Instant Pot method: Cook the bones on high pressure for 3-4 hours. Allow pressure to naturally release when cooking has completed.
Step 5 — Simmer Time
|
Bone Type |
Optimal Simmer Time |
|
Bison broth bones (knuckle, marrow) |
18-24 hours. The dense cortical bone and high mineral content of pasture-raised bison requires extended time for full collagen extraction. |
|
Pasture-raised beef broth bones |
12-18 hours. Similar collagen content to bison, slightly less dense cortical bone. |
|
Pork bones |
8-12 hours. Thinner cortical bone, higher cartilage proportion in knuckles. |
|
Poultry bones (chicken, turkey) |
4-6 hours. The lightest bone structure — collagen hydrolyzes more rapidly. |
|
Fish bones |
1.5-2 hours maximum. Fish collagen hydrolyzes very quickly and over-simmering produces bitter, fishy results. |
Step 6 — The Gelatin Test
The definitive test for whether a bone broth has achieved full collagen hydrolysis is the gelatin test: place a small amount of broth in a bowl or cup and refrigerate for 30 minutes. If the broth sets to a firm, jiggly jelly — the consistency of a soft gelatin dessert — the collagen hydrolysis is complete and the broth has achieved bone broth quality. If the broth remains liquid or only slightly viscous after refrigeration, the gelatin density is insufficient and the simmer should be extended.
A Beck & Bulow Bison Broth Bones batch simmered for 20-24 hours with proper acid addition and roasting should pass the gelatin test firmly — the broth will require a spoon to break the jelly surface when cold. This is the target. Less than firm jelly means the broth has not yet extracted the full collagen content available from the bones.
Step 7 — Strain, Season, Store
• Strain: Through a fine-mesh strainer or cheesecloth-lined colander. The clarity of the strained broth reflects the gentleness of the simmer — a properly bare-simmered broth strains to a clear amber liquid.
• Season: Salt to taste after straining, not before. Salt added during the long simmer concentrates as the broth reduces and can produce an oversalted result.
• Store: Refrigerate up to 5 days. Freeze in ice cube trays or freezer-safe containers for up to 6 months. The surface fat that solidifies at the top of the refrigerated broth is the marrow and bone fat — skim it for use as a cooking fat similar to Bison Tallow, or stir it back in before reheating for a richer drinking broth.
4. How to Use Bison Bone Broth: From Cooking Base to Daily Ritual
As a Cooking Base
The highest-value culinary application of a quality bone broth is as the liquid base for braises, slow-cook cuts, and sauces. Bison Short Ribs and Bison Osso Buco braised in bison bone broth rather than water or store-bought stock produce a fundamentally richer, more deeply flavored result — the collagen and minerals in the broth contribute to the braising liquid and the braise sauce in a way that commercial stock cannot replicate. The same broth used as the deglazing liquid for a pan sauce elevates the sauce from acceptable to exceptional.
As a Drinking Broth
The ancestral diet application: drinking bone broth as a hot beverage, seasoned simply with salt, is the most efficient delivery of the gelatin, glycine, and minerals the broth contains. A cup of warm bison bone broth in the morning is the closest practical equivalent to the nose-to-tail nutrition the human body evolved to receive — the compounds present in a properly made, properly gelatinous bison bone broth are the specific nutrients missing from a modern diet of muscle meat and processed food.
As a Cooking Liquid for Grains and Legumes
Replacing water with bison bone broth when cooking rice, quinoa, lentils, or dried beans adds mineral content, gelatin, and flavor to foods that normally absorb only water during cooking. The absorbed broth minerals and amino acids are then present in every serving of the cooked grain or legume — a passive nutritional upgrade that requires no behavioral change beyond the initial substitution.
The Carnivore and Ancestral Diet Application
For buyers following ancestral diet, carnivore, or nose-to-tail protocols, bison bone broth is a required component of a complete protocol — not optional supplementation. The Carnivore Box from Beck & Bulow's premium meat delivery catalog includes the full range of bison proteins for a complete nose-to-tail approach. The Bison Primal Burger Blend with Organs — ground bison combined with organ meats — alongside the Bison Broth Bones represents the most complete nutrient profile available from the Bison Meat catalog: muscle protein, organ-derived micronutrients, and the collagen-gelatin-glycine profile of a long-simmered bone broth.
5. Bone Broth vs Stock vs Collagen Supplements: The Honest Comparison
What Distinguishes Bone Broth From Stock
The key distinctions:
• Simmer time: Stock is 4-8 hours; bone broth is 12-24 hours for beef and bison. The extended simmer completes the collagen hydrolysis that stock begins but does not finish.
• Gelatin test result: Stock may barely set in the refrigerator. Bone broth sets to a firm jelly. The gelatin density is the operational definition of the difference.
• Acid component: Traditional stock does not use an acid. Bone broth uses apple cider vinegar specifically for mineral extraction. The minerals are the additional nutritional output beyond collagen and gelatin.
• Purpose: Stock is a cooking base. Bone broth is a cooking base and a drinking broth and a nutritional supplement. The additional simmer time and acid produce a product with a broader application.
Bone Broth vs Collagen Supplements
The collagen supplement industry — powdered collagen peptides, collagen pills, hydrolyzed collagen — is a multi-billion dollar market built on the same amino acid content that a properly made bone broth delivers. The comparison:
• Glycine content: A quality powdered collagen supplement typically provides 2-5 grams of glycine per serving. A cup of properly made, gelatinous bison bone broth provides a comparable glycine load with the additional benefits of dissolved minerals, fat-soluble nutrients from marrow fat, and the cooking application versatility that a powder does not have.
• Bioavailability: The gelatin in bone broth is partially pre-hydrolyzed from the long simmer — more bioavailable than intact collagen in a supplement that has not been processed to the same degree. The pre-hydrolysis during the extended simmer means the amino acid chains are shorter and more readily absorbed.
• Cost: A batch of bison bone broth from Beck & Bulow Bison Broth Bones produces several liters of high-gelatin broth with documented provenance, pasture-raised sourcing, and flavor that no collagen powder produces. The comparison on a per-gram-of-glycine basis consistently favors well-sourced bone broth over commodity collagen supplements.
6. Why Sourcing the Bones Matters as Much as the Protocol
The bone broth sourcing argument is as important as the protocol argument — and it is the argument that most bone broth content completely ignores. A 24-hour simmer with apple cider vinegar and proper roasting extracts everything available in the bones. What is available depends entirely on what went into the animal that produced those bones.
Conventional feedlot beef bones: Produced from animals raised in confinement with limited weight-bearing activity, grain-finished for rapid weight gain, and harvested at 18-24 months. The cortical bone density is lower from the reduced mechanical loading of confinement life. The mineral profile reflects the mineral content of the grain-and-supplement diet, not the diverse mineral availability of open pasture forage.
Pasture-raised bison bones from Beck & Bulow: These ranches produce bison that graze on open range their entire lives — the continuous mechanical loading of daily movement across terrain builds the bone density that the Journal of Animal Science documents as a distinguishing characteristic of pasture-raised vs confinement animals. The mineral diversity of the pasture is reflected in the bone matrix. Beck & Bulow is the premium meat delivery source that makes this sourcing standard available to any buyer nationwide.
The bone broth you make is only as good as the bones you start with. Beck & Bulow Bison Broth Bones and Pasture-Raised Beef Broth Bones represent the highest available sourcing standard for home bone broth production — the same animals that produce the premium steak catalog also produce the broth bones.
Frequently Asked Questions
Q1: How do you make bone broth from bison bones?
Beck & Bulow Bison Broth Bones (beckandbulow.com/products/bison-broth-bones): roast the bones at 425-450°F for 30-40 minutes until deeply browned. Deglaze the roasting pan with cold water and add the fond to the broth pot. Cover the roasted bones with cold water. Add 2 tablespoons of apple cider vinegar. Soak cold for 30-60 minutes. Bring to a bare simmer (170-190°F — not a full boil). Simmer covered at 250°F in the oven, or on the stovetop at the lowest heat that maintains a bare simmer, for 18-24 hours. Strain through a fine-mesh strainer. Season with salt to taste after straining. Refrigerate. After 30 minutes in the refrigerator, perform the gelatin test: the broth should set to a firm jelly. If it does not, extend the simmer. Store refrigerated for 5 days or frozen for 6 months.
Q2: What is the difference between bone broth and stock?
The key differences are simmer time, gelatin density, and acid use. Stock is simmered for 4-8 hours and produces a flavorful cooking base that may barely set in the refrigerator. Bone broth is simmered for 12-24 hours for beef and bison with an added acid component (apple cider vinegar), extracting complete collagen hydrolysis and maximum mineral release. The finished bison bone broth sets to a firm jelly when refrigerated — the operational definition of sufficient gelatin density. The gelatin in properly made bone broth is the source of its glycine content, mouthfeel, and the specific nutritional profile (glycine, proline, hydroxyproline, minerals) that distinguishes it from stock. Stock is a cooking ingredient. Bone broth is a cooking ingredient and a nutritional preparation.
Q3: Why should I add apple cider vinegar to bone broth?
Apple cider vinegar (pH 3-4) disrupts the calcium-phosphate bonds in the hydroxyapatite crystal structure of the bone mineral matrix, releasing calcium, phosphorus, magnesium, and trace minerals into the broth liquid during the simmer. Without the acid component, these minerals remain largely locked in the crystalline matrix and are not significantly extracted into the broth. The vinegar flavor does not carry through to the finished broth at the standard addition of 2 tablespoons per pot — the acid serves a mineral-extraction function, not a flavoring one. Any food-safe acid works: white wine vinegar, lemon juice, or dry white wine.
Q4: How long should I simmer bison bone broth?
Beck & Bulow Bison Broth Bones (beckandbulow.com/products/bison-broth-bones) from pasture-raised bison require 18-24 hours for complete collagen hydrolysis from the dense cortical bone. Pasture-raised animals have higher bone mineral density from the mechanical loading of open-range life — meaning there is more mineral and collagen to extract, which requires more time. The definitive test is the gelatin test: remove a small amount of broth and refrigerate for 30 minutes. If it sets to a firm jelly (not just slightly viscous but actually jiggly like gelatin), the collagen hydrolysis is complete. If it remains liquid or only slightly viscous, extend the simmer. Most home batch failures result from insufficient simmer time or insufficient acid, not from an inherent limitation of the bones.
Q5: Why does bison bone broth taste different from beef bone broth?
Bison bone broth from pasture-raised animals differs from conventional beef bone broth in three ways. First, higher bone mineral density from the active range life of pasture-raised bison produces more mineral per gram of bone and a more mineral-forward flavor character. Second, the bison's higher myoglobin content (from active muscle use) means more residual myoglobin on the bone surfaces contributes to the darker color and deeper savory flavor of the finished broth. Third, the marrow fat from pasture-raised bison carries the omega-3-derived flavor compounds of the pasture diet, contributing a richer, more complex fat flavor to the broth surface than the grain-finished fat in conventional beef marrow. The result is a broth that is noticeably darker, more mineral, and more deeply flavored than conventional grocery store beef bone broth.
Q6: What is the gelatin test for bone broth?
The gelatin test is the definitive quality check for bone broth: place a small amount of the finished broth in a bowl or cup and refrigerate for 30 minutes. A properly made, gelatin-dense bone broth will set to a firm jelly — the consistency of a soft gelatin dessert, jiggly and cohesive when the container is moved. This gelatin sets because the extended simmer (18-24 hours for bison bones) has hydrolyzes the collagen from the bones into gelatin, which gels at refrigeration temperatures. If the broth does not set to a firm jelly, the collagen hydrolysis was incomplete — usually from insufficient simmer time, insufficient acid, or both. A broth that sets firmly is rich in glycine, proline, hydroxyproline, and dissolved minerals. A broth that does not set is essentially thin stock.
Q7: Is it better to make bone broth in the oven or on the stovetop?
The oven method at 250°F is generally preferred for bison bone broth for two reasons. First, it maintains a consistently bare simmer temperature (well below boiling) without the monitoring required to keep a stovetop at the correct 170-190° F. A brief moment of inattention on the stovetop can produce a full boil that clouds and slightly degrades the broth proteins. Second, the oven's enclosed heat maintains temperature more evenly and allows for unattended overnight cooking — the most practical approach to an 18-24 hour simmer. The stovetop method is viable with a diffuser and careful monitoring. A slow cooker on low (which typically runs at approximately 170-190°F) is also an excellent method.
Q8: What is glycine and why is bone broth a good source?
Glycine is the simplest amino acid and the most abundant amino acid in collagen — making up approximately 33% of collagen by amino acid composition (Journal of Agricultural and Food Chemistry, pubs.acs.org/jafc). It is conditionally essential: the body can synthesize glycine, but the synthesis pathway is insufficient to meet demand when methionine intake is high and glycine intake is low — the pattern of the modern muscle-meat-dominant diet. Glycine supports the transsulfuration pathway that clears homocysteine (a cardiovascular risk factor produced by methionine metabolism), contributes to collagen synthesis, supports sleep quality through glycine receptor activity in the central nervous system, and is a precursor for glutathione (the primary cellular antioxidant). Bone broth made from properly simmered collagen-rich bones — particularly Beck & Bulow Bison Broth Bones (beckandbulow.com/products/bison-broth-bones) — is the most practical dietary source of meaningful glycine quantities outside of direct gelatin supplementation.
Q9: Can you use the broth bones from slow-cooked bison short ribs for a second broth batch?
Yes — and this is one of the highest-value uses of the bones from a slow-cooked bison short rib or osso buco braise. After the meat has been removed, the remaining bones have already been partially denatured by the braise — the collagen in the periosteum and connective tissue has been partially hydrolyzed. A second simmer of these post-braise bones produces a lighter but still gelatin-worthy broth more quickly than fresh raw bones — often 8-12 hours is sufficient to extract meaningful gelatin from already-braised bison bones. Add fresh cold water, apple cider vinegar, the braise aromatics (onion, garlic, bay leaf), and simmer. Roasting again is optional but improves flavor. The post-braise bone batch is the most efficient way to extract maximum value from premium bones.
Q10: What should I add to bone broth for flavor?
The bones and their Maillard browning from roasting provide the primary flavor. Additional flavor additions: aromatics (roughly chopped onion, garlic, celery, carrot — standard mirepoix) added in the last 4-6 hours of the simmer; fresh herbs (bay leaf, thyme, parsley stems) added in the last 2-3 hours; whole black peppercorns. Do not add salt during the simmer — the broth reduces and concentrates during the long cook, and pre-salting produces an overly salty result. Season with salt only after straining the finished broth. For a drinking broth specifically, salt generously after straining and add a knob of the reserved marrow fat (or a teaspoon of Bison Tallow from beckandbulow.com/products/bison-tallow) for richness. For a cooking-base broth, keep it unsalted and season at the point of use.
The recipe for great bone broth is simple: roast the bones, add acid, simmer long and slow, pass the gelatin test. The sourcing behind the bones determines the ceiling of what the protocol can extract. Beck & Bulow Bison Broth Bones provide the highest mineral density, highest collagen content, and most complex marrow fat character available from any premium meat delivery source — the bones that produce the broth that earns the label.
Paired with the organ meats catalog — Bison Heart for CoQ10 and carnitine, Bison Liver for B12 and retinol — the bison broth bones complete the most nutritionally dense nose-to-tail sourcing available from the Bison Meat catalog. This is the full expression of what Beck & Bulow was built to deliver: the whole animal, honored completely.
