Stocks & broths

white stock

fond blanc · A clear, pale, flavorful liquid made by gently simmering blanched bones with aromatics. It is the neutral foundation upon which most classical sauces, soups, risottos, and braises are built. Its virtue is versatility: unlike brown stock, it contributes no color, allowing the finished dish to set its own palette.

Family · Stocks & brothsDifficulty · EasyMake-ahead · YesYield · 2 kg blanched poultry bones + 4 L water + 300–400 g mirepoix → ≈3.5 L finished stock (reduced by ≈12–15 %)

The formula

1 kg blanched bones : 2 L cold water : 150–200 g mirepoix

The governing proportion is the water‑to‑bone ratio of 2:1 by volume (≈2 L per kg of bones). Mirepoix is added at roughly 15–20 % of the bone weight (150–200 g per kg). The stock should be covered by 5–7 cm of cold water before the simmer begins; top up with cold water if significant evaporation occurs during cooking.

Identity

  • Bones are blanched before use to purge blood and impurities that would cloud the stock
  • Started in cold water, brought slowly to a bare simmer (82–90 °C), never boiled
  • Aromatics added: mirepoix (onion‑dominant, carrot, celery) + bouquet garni
  • Cooked 3–4 hours for poultry, 4–6 hours for veal or beef
  • Degreased and strained through a fine‑mesh sieve lined with damp muslin before use or storage

Ingredients

BaseBlanched poultry, veal, or beef bones (with 10–20 % meat for flavor)Bones must be blanched: cover with cold water, bring to a boil, drain, and rinse — this is non‑negotiable for clarity
LiquidCold waterAlways start in cold water to extract impurities gradually and promote a clear result
AromaticsMirepoix: onion (stubborn), carrot (sweet), celery (savory)Classical ratio 2:1:1 or 3:2:1 onion‑dominant. 150–200 g total per kg of blanched bones
AromaticsBouquet garni: bay leaf, thyme, parsley stemsAdded whole, tied in cheesecloth; removed before straining. Over‑cooking extracts bitter tannins.
SeasoningCoarse salt (added sparingly at end)Salt slightly inhibits collagen extraction; season lightly at the end because the stock may reduce in later applications.
SeasoningWhite peppercorns (optional)Added to bouquet garni or directly; black pepper may impart a pale gray tint.

Method

  1. 1Blanch the bones: place raw bones in a stockpot, cover with cold water by 5 cm, bring to a full boil over high heat, and boil vigorously for 5 minutes.Rapid coagulation of proteins and expulsion of blood at the boil purges the bones of impurities that would otherwise cloud, bitter, and darken the stock.
  2. 2Drain the blanched bones, rinse them under cold water, and clean the pot.Rinsing removes the gray scum that adhered to the bones during blanching; a clean pot prevents residual impurities from re‑entering the stock.
  3. 3Return blanched bones to the pot. Add cold water to cover by 5–7 cm. Add the mirepoix and bouquet garni.Starting in cold water rather than hot allows a gradual, controlled extraction of collagen and flavor compounds; hot water would seal bone surfaces and reduce yield.
  4. 4Place over medium‑low heat and bring to a bare simmer — a few lazy bubbles breaking the surface at 82–90 °C. Skim continuously for the first 20–30 minutes.A full boil agitates the liquid, forcing suspended fat and protein through the stock and making it cloudy. A bare simmer keeps it crystal‑clear while still extracting gelatin and flavor.
  5. 5Maintain the bare simmer, uncovered or with lid ajar, for 3–4 hours (poultry) or 4–6 hours (veal/beef). Add cold water only if the level drops more than 5 cm below the bones.Extended gentle simmering slowly dissolves collagen into gelatin, creating body. Adding cold water mid‑cook resets extraction; topping up with hot is acceptable but cold is safest.
  6. 6Remove from heat. Strain through a fine‑mesh sieve lined with damp muslin. Degrease the finished stock using a ladle or fat separator.Fine straining removes all solid matter for clarity. Removing fat prevents rancidity during storage and gives the cook control over fat content in the final dish.
  7. 7Cool the stock rapidly in an ice bath (blast‑chill in a clean, sanitized container). Refrigerate at ≤4 °C.Rapid cooling prevents the stock from lingering in the danger zone (4–60 °C) where bacteria proliferate. A properly cooled stock keeps for 5 days.

Techniques that matter

Blanching and purging

Essential for clarity and flavor purity. Boiling the bones in a separate step removes blood, albumen, and mucilaginous impurities that would otherwise cloud and flavor the stock unpleasantly.

Bare simmer (82–90 °C)

Prevents agitation of suspended particles that would make the stock cloudy. At this temperature range collagen dissolves into gelatin efficiently without turbulence.

Degreasing

Fatty stock spoils faster and cannot be accurately seasoned. In classical cuisine degreasing is done by skimming during cooking and/or using a fat separator at the end.

Straining through muslin

Muslin traps finer particles than a standard sieve, producing a perfectly clear liquid essential for refined sauces and aspics.

Variations & derivatives

Chicken white stock (fond blanc de volaille)French classical

Most common household white stock. Use backs, necks, and wings with a small amount of leg or thigh meat. Simmer 3 hours. The benchmark against which all others are measured.

Veal white stock (fond blanc de veau)French classical

Made from veal knuckle and bones. Longer cooking (5–6 hours) required for the denser collagen of mature bones. Produces the richest gelatinous body. The standard for classical demi‑glace production.

Fish stock (fond de poisson)French classical

Not technically ‘white stock’ but often grouped here. Made from fish bones and heads (never oily fish), no blanching required. Simmered 20–30 minutes only. Aromatics are gentler: fennel, leek, mushroom trimmings, no carrot. White wine optional.

DashiJapanese

Kombu and katsuobushi based; technically a stock but operationally different. Cold steep kombu, then heat briefly; steep katsuobushi and strain. Not a simmered bone stock, but functionally a white/clear stock base.

Mirepoix variée / White mirepoix stockFrench classical

Replace standard mirepoix with white mirepoix (raw, uncaramelized onion, celery, and mushroom trimmings) for an even paler stock used in white sauces and vol‑au‑vent.

Used in these dishes

Velouté sauce · The liquid base; white stock + blonde roux is the foundation of veloutés of chicken, veal, or fishRisotto alla Milanese · The sole liquid medium for rice; stirred in gradually as the starch releasesRice pilaf (pilaf) · The cooking liquid into which rice is toasted, giving it aromatic depth beyond what water providesBraised dishes (coq au vin blanc, blanquette) · The braising liquid; must have enough body to carry the dish’s sauce when reducedThin soups and consommes · The unflavored canvas to which purées, garnish, and clarified consommé raft are addedSauce Béchamel (variant Béchamel à la vapeur) · White stock is added to the milk base for extra depth in the variant Béchamel à la vapeurSoupe à l’oignon · The liquid in which the onion fondue is diluted to make the classic French onion soup base

Substitutions

  • White stockWater with a bouillon concentrate or cubeReconstitutes the liquid but lacks gelatin body and aromatic depth. Only acceptable as a last resort for braising or boiling where the dish contributes its own flavor.changes result
  • Veal white stockChicken white stockLighter in body and flavor. Acceptable in recipes where the veal flavor is incidental, but insufficient for demi‑glace or classical braised dishes.changes result
  • Chicken white stockStore‑bought unsalted chicken brothVariable quality; most commercial broths lack gelatin and contain sodium. Use at 80 % strength and adjust seasoning carefully.changes result

Troubleshooting

Stock is cloudy and opaque

Boiling (rather than simmering) during cooking, or bones not blanched before useNext batch: blanch bones rigorously and maintain a bare simmer. This batch: strain through a fine‑mesh sieve lined with muslin; bring to a boil with a raft of egg whites (fining) if clarity is critical, or accept it for use in non‑sauce applications

Stock is greasy and tastes of fat

Fat not removed before storage, or bones were too fatty and not trimmedSkim fat from the surface with a ladle or paper towel before storage. For a finished dish, use a fat separator or chill the stock and lift the solidified fat off the surface

Stock is weak, watery, and flavorless

Too much water relative to bones, insufficient cooking time, or insufficient aromaticsReduce the finished stock by one‑third to concentrate flavor; add more aromatics (mirepoix, bouquet garni) at the reduction stage if making a fresh batch

Stock tastes bitter or acrid

Bouquet garni cooked too long (bitter tannins), or stock boiled over and picked up burnt flavor from the pot baseStrain immediately; add a raw potato or piece of bread to absorb bitterness for 5 minutes, then discard. Future batches: remove bouquet garni after 2 hours and never let the stock contact a dry, overheated pot

Storage

Keeps 5 days refrigerated at ≤4 °C; 6 months frozenRefrigerate in airtight containers with minimum headspace. For freezing, use ice‑cube trays for small portions or rigid containers with 2 cm of headspace. Do not store in reactive metal containers. Reheat: Gently, in a saucepan over medium‑low heat to a full simmer. Do not boil. If frozen, thaw overnight in the refrigerator; never microwave for quality stocks.
