Stocks & broths
Consommé
Consommé · A perfectly clear, deeply flavored stock that has been purified through controlled heat‑coagulation of a protein raft. The raft acts as a living filter: egg whites denature and rise to the surface as a porous mass, trapping suspended fat globules and particulate matter while allowing the clarified liquid to pass through perfectly transparent. The result is a stock of absolute clarity and concentrated flavor intensity that represents the apex of classical stock craft.
The formula
1 L stock : 60–90 g egg whites
One raft clarifier per 1–1.5 L finished consommé. Use 2–3 egg whites (≈60–90 g) per liter of stock. The raft must be cold when added to cold stock; heat very gradually over 45–60 min to 82–85 °C. Yields roughly 750–850 mL clarified liquid from 1 L starting stock due to absorption by the raft.
Identity
- A transparent, amber liquid through which light passes without obstruction or haze
- A flavor density substantially greater than the unclarified stock — the raft concentrates and purifies simultaneously
- A clean, pure taste of the original meat or poultry with no trace of bitterness or starch
- No visible fat globules at the surface or suspended in the body of the liquid
- A clean, rounded finish with the aromatics lending secondary notes, never dominating
Ingredients
| Base | Brown or white stock (beef, chicken, veal, or game) | The foundation; use the highest‑quality stock available. Brown consommé starts with a well‑reduced, deeply colored brown stock. Strength directly determines final quality. |
| Binder | Egg whites | The clarifying agent. Proteins denature at 62–68 °C, forming a three‑dimensional coagulum that traps impurities. Use 2–3 whites per liter. Whites only, not whole eggs, to avoid emulsified fat. |
| Aromatics | Mirepoix (onion, carrot, celery 2:1:1) | Provides aromatic complexity. For brown consommé, the vegetables are often roasted first. Classical French also includes tomato concassée for brown consommé to deepen color and add subtle acidity. |
| Acid | Tomato paste or concassée (for brown) | Adds acidity and helps drive the clarification by denaturing proteins more aggressively. Essential for traditional brown consommé; omit for white consommé. |
| Seasoning | Kosher salt, white pepper, fresh thyme, bay leaf, parsley stems | Seasoning is adjusted after clarification, once the liquid is fully purified and tasted in isolation. |
| Liquid | Cold water or cold stock for the raft slurry | The egg whites are beaten to a loose foam with cold water before being stirred into the cold stock. Cold prevents premature coagulation before full integration. |
Method
- 1Prepare the raft: beat 2–3 egg whites per liter of stock to a loose, glossy foam with a pinch of salt and 2–3 volumes of cold water.Egg whites achieve maximum air incorporation and protein dispersion when beaten cold. The foam creates enormous surface area for the clarifying action and ensures even distribution through the cold stock.
- 2Combine cold stock, egg white foam, and aromatics (mirepoix, tomato, herbs) in a wide, heavy pot. Stir gently to integrate the raft completely.The entire liquid must be cold before the raft is added. Adding warm or hot causes the proteins to coagulate in clumps rather than forming an even, porous raft across the surface.
- 3Heat extremely slowly over medium‑low flame — ideally 45–60 minutes — to reach 82–85 °C (180–185 °F). Do not stir after heating begins.Gradual heating allows the egg‑white proteins to denature uniformly and bond with fat and impurities as they rise. Agitation at this stage destroys the forming raft structure, releasing trapped particles back into the liquid.
- 4Once the raft has fully formed and set on the surface (it should feel like a firm, dry omelet), reduce heat to its lowest setting. Poke 2–3 small holes in the raft with a spoon handle to allow clarified liquid beneath to seep through.The raft is a self‑filtering membrane. Holes allow the now‑clean liquid to escape; the raft continues to trap impurities as the liquid percolates through the porous protein structure.
- 5Ladle the clarified consommé carefully from beneath the raft — never disturb the raft itself — into a clean pot. Strain through a fine chinois lined with damp cheesecloth for final polishing.The first portions drawn are the least clarified; the cheesecloth catches any remaining fine particulate that passed through the raft. Puncturing the raft before ladling prevents vacuum‑lock and ensures steady, controlled flow.
- 6Season the finished consommé precisely. Adjust salt, add a tiny squeeze of lemon if needed for brightness. Serve immediately or store.Clarification concentrates flavor — the seasoned consommé will taste more intense than the original stock. Lemon brightens and lifts the palate but is optional; classical consommé is not acidic.
Techniques that matter
Protein coagulation (clarification)
Egg‑white proteins denature and aggregate, forming a mesh that selectively traps fat and suspended solids while allowing water and dissolved aromatics to pass through — a natural membrane filtration using heat as the trigger.
Controlled temperature management
The 82–85 °C window is critical: hot enough to fully coagulate the proteins and set the raft firmly, cool enough to avoid churning the liquid or producing a curdy, broken raft that releases impurities back into the stock.
Percolation through a raft
The raft acts as a gravity‑fed filter; the liquid beneath it, now purified, is drawn off through small holes. The principle is identical to percolation coffee — but the filter medium is living protein that actively bonds with impurities.
Dégraissage (fat removal)
Any fat remaining in the stock before clarification will be trapped by the raft and removed with it — making consommé the most complete fat‑removal technique in classical cooking, superior to simple skimming.
Variations & derivatives
Consommé MadrilèneFrance (classical French, named for Madrid)
Brown beef consommé tinted deep amber‑red with tomato paste. Served cold in aspic or hot as a primer course. The tomato provides both color and a subtle acidity that lifts the beef depth.
Consommé CélestineFrance (classical French)
Consommé served with thin, delicate savory pancakes (crêpes Célestine) cut into julienne and floated in the bowl. The contrast of clear broth against ivory ribbons is the visual signature.
Consommé with quenellesFrance (classical French)
Small, light marrow or fish quenelles poached directly in the consommé — the consommé both cooks the quenelles and serves as the surrounding sauce. A two‑in‑one technique.
Potage Saint‑GermainFrance
Green pea purée served in consommé style with a raft of herb butter floated on top — a savory interpretation using the clarity principle with a purely vegetable base.
Thai nam ya curry consomméThailand
A coconut milk and fish‑based consommé clarified with egg whites — Southeast Asian application of the classical French technique with galangal, kaffir lime, and Thai basil aromatics.

Substitutions
- Egg white clarifier → Isinglass (fish bladder gelatin) — Traditional pre‑1910s method. Dissolved isinglass creates a floating gelatinous raft with less aggressive protein bonding — produces a softer clarification, less suitable for very fatty stocks.
- Egg white clarifier → Ground lean beef or game — For very large volumes, raw ground lean beef (beaten to a paste) can substitute for egg whites — it performs the same coagulation‑impurity bonding. Used historically for meat‑based consommés.
- Beef stock → Chicken or veal stock — Chicken consommé is lighter, more delicate; veal consommé is richer and more buttery in texture. The technique is identical but the flavor profile shifts entirely. Do not substitute a pre‑made commercial broth — lack of gelatin and depth will produce a thin, flat result.changes result
Troubleshooting
Raft fails to form — whites scatter in clumps across the surface or sink to the bottom
Temperature rose too quickly, causing proteins to coagulate before rising and bonding into a unified raft. Or the egg whites were not properly beaten to incorporate air before adding to cold stock. → Start over with a new batch. Ensure the stock is truly cold (below 10 °C) before adding the raft. Heat at the absolute lowest flame for a full 45–60 minutes to reach 82–85 °C. Never stir once heating begins.
Consommé is cloudy or hazy despite raft formation
The raft was disturbed during cooking (stirring, bumping, boiling), breaking the filter structure and releasing trapped particles back into the liquid. Or the stock was too fatty before clarification. → Strain through a double layer of damp cheesecloth in a fine chinois. For future batches, degrease the stock more aggressively before adding the raft — the raft removes fat but cannot overcome gross fat contamination. Reduce heat and re‑clarify with a fresh raft if the liquid is valuable enough.
Raft sinks or partially collapses during cooking
Too few egg whites for the volume; proteins insufficient to support the raft structure. Or the stock had excessive suspended solids that added weight beyond the raft's carrying capacity. → Use 3 egg whites per liter minimum, especially for stocks with high particulate load. Ensure aromatics are cut small and evenly to reduce particulate load. A sunken raft can be rescued by carefully ladling off the liquid, discarding the spent raft, and starting a new clarification with fresh egg whites.
Consommé tastes flat or one‑dimensional despite good clarity
The original unclarified stock was weak or of poor quality. Clarification concentrates and purifies — it cannot create flavor that was absent to begin with. The raft strips some surface‑active compounds that contribute to perceived mouthfeel and roundness. → Use a deeply flavored, well‑reduced stock as the starting material. For brown consommé, ensure the mother stock was built with roasted bones, reduced Maillard products, and a proper wine deglaze. Post‑clarification, a tiny pinch of xanthan gum (0.1 %) can restore body without affecting clarity.
