7.2 White Stocks, Brown Stocks & Broths

Quick Answer: Make white stocks without roasting for pale colour; roast bones and aromatics for brown stocks; simmer gently for the right time by protein; skim and strain cleanly; use stock as a building block and broth as a seasoned, meat-forward liquid.

Task D-13 expects you to produce white stocks, brown stocks, and broths with correct colour, body, and flavour. Procedural questions dominate: what went wrong when chicken stock turned muddy, why fish stock tastes bitter, how long to simmer roasted beef bones, or whether a recipe needs stock or broth.

White Stocks

White stock (fond blanc) extracts flavour without roasting bones to brown. The liquid stays pale so it can support blond sauces (velouté), cream soups, and light braises.

Chicken White Stock

Use carcasses, necks, backs, and wing tips. Optional blanching yields a cleaner flavour for fine work. Cover with cold water, bring slowly toward a simmer, skim foam aggressively at the start, add white or standard mirepoix and a bouquet/sachet, then maintain a gentle simmer about 3–4 hours. Strain, degrease, cool.

Do not boil. Boiling emulsifies fat into a cloudy, greasy liquid. Do not add floury vegetable scraps that disintegrate into starch haze.

White Veal or Beef Stock

Younger veal bones give classic pale body for white sauces. Blanch bones for cleanliness when required by house method. Simmer longer than chicken—often in the 4–6 hour range depending on bone size—still without roasting. Use white mirepoix when colour must stay blond.

Fish Stock / Fumet

Fish fumet is a concentrated white fish stock. Use lean white fish bones and heads with gills removed. Sweat aromatics lightly in butter or oil (sometimes with mushroom), add bones, cover with water or a splash of white wine then water, bring to a simmer, skim, and cook only about 30–45 minutes. Longer cooking extracts bitter, gluey notes and greys the liquid.

Avoid oily fish (mackerel, salmon) for classic clear fumet unless a recipe specifically wants that flavour. Strain through fine cloth for sauce work.

Vegetable Stock

Vegetable stock has no bones, so it will not gel from gelatin. Build flavour with onion, leek, celery, carrot, mushroom, tomato, herbs, and peppercorns. Avoid overloading cabbage-family vegetables if you need a neutral base—they dominate. Simmer roughly 45–60 minutes until aromatic and lightly sweet; overcooking turns vegetables sour and muddy. Roast vegetables first only when you want a darker, sweeter profile (then you are edging toward a brown vegetable stock).

Brown Stocks

Brown stock (fond brun) starts with roasted bones—typically beef or veal knuckle, shank, and neck—and roasted mirepoix. Deep brown colour and roasted flavour feed espagnole, demi-glace, gravies, and braising liquids.

Procedure outline:

1. Roast bones in a hot oven until deeply browned, not blackened.
2. Transfer bones to a stockpot; degrease the roasting pan and deglaze with water or stock, scraping fond into the pot.
3. Add tomato product (paste browned on bones or with vegetables is common) for colour and mild acidity.
4. Cover with cold water, bring to a simmer, skim.
5. Add roasted or separately browned mirepoix and aromatics.
6. Simmer gently about 6–8 hours (or longer for very large bones), skimming as needed.
7. Strain without pressing sludge; degrease; cool safely.

Exam trap: Black, acrid roasted bones make bitter stock. There is no reliable fix—restart with properly browned bones. Another trap: calling a brown stock “done” after one hour; collagen and roasted flavour need time.

Chicken bones can be roasted for a brown chicken stock used in darker sauces and gravies; know that white chicken stock remains the default for blond applications.

Simmer Times at a Glance

Times are training ranges, not stopwatch law—bone size, pot size, and desired concentration matter—but exam answers expect the relative order: fish short, poultry medium, brown beef longest.

Skimming, Degreasing, and Finishing

Skimming removes coagulated proteins and scum that rise early. Skim early and often; later skimming also removes excess fat if you are not chilling to lift a fat cap.

Degreasing matters for clean mouthfeel and for sauces that would otherwise look oily. Chill overnight and lift the solid fat sheet when practical, or ladle/use a fat separator for same-day service.

Seasoning: keep stocks under-salted. Broths and finished soups get final salt. Acid (wine, tomato) in brown stocks is balanced and cooked; raw harsh wine notes mean insufficient reduction or simmering.

Strain through a chinois. For crystal-clear applications, line with cheesecloth. Never squeeze the solids hard if clarity is the goal.

Cool in ice baths or shallow pans. Large stockpots left at room temperature spend dangerous time between 60°C and 4°C. Reheat service portions rapidly to safe hot-holding temperatures per your jurisdiction’s food retail/food services rules.

Broth vs Stock

Chicken broth might simmer bone-in pieces or stewing hens with aromatics and salt until the meat is done and the liquid tastes finished. Beef broth similarly starts from meaty cuts. You can fortify broth with stock for body, or dilute rich stock into a broth-style soup with vegetables and seasoning.

On the exam, if the cook needs unseasoned liquid that will reduce by half into a sauce, choose stock. If the item is “beef broth soup” served in a cup with vegetables, the liquid should taste seasoned and meaty like broth.

Quality Checks Before You Plate or Sauce

• Colour: white stocks pale; brown stocks deep brown without burnt edge.
• Aroma: clean, meaty or roasted—not sour, sulphurous, or fishy-bitter.
• Body: coats lightly; gels when cold for bone stocks.
• Clarity: appropriate to use (rustic stew vs consommé).
• Salt: low enough for further cookery.

Commercial bases appear in many kitchens; Red Seal still expects you to know scratch method, ratios, and troubleshooting so you can evaluate and adjust convenience products when used.

Master white versus brown procedure, relative simmer times, skimming discipline, and the stock/broth distinction—those four themes drive most D-13 application items.
