Consommé Clarification (Lean Meat to Stock)
Also: clearmeat raft, consommé clarification ratio, clearmeat method, clarification mixture
200g lean ground meat + 1 egg white + 30ml acid per 1 litre of cold, defatted stock — the clearmeat raft that transforms cloudy stock into brilliant consommé.
Consommé clarification is a classical French technique in which a mixture of lean ground meat, egg whites, aromatic vegetables, and acid (the 'clearmeat' or clarification mixture) is stirred into cold, defatted stock. As the mixture heats, proteins from the ground meat and egg whites coagulate into a porous raft that rises to the surface, trapping colloidal particles and clarifying the liquid below to diamond-like brilliance. The ratio governs how effectively the raft forms and how robustly it captures impurities.
The proportions
- 200g per litre
- Lean ground meat (same species as stock) — Beef shin for beef consommé, ground chicken breast for white consommé, ground veal for fond de veau; lean is essential — fat inhibits raft formation
- 1 large white (about 30g) per litre
- Egg whites — Provide additional albumin protein; can be increased to 2 whites per litre for stock that is very cloudy
- 80g per litre
- Mirepoix brunoised fine — Onion, carrot, celery in classic 2:1:1 ratio; tomato (40g per litre) adds acid and red colour that aids clarification
- 30–40ml per litre
- Acid (tomato, wine, or lemon juice) — Accelerates protein denaturation and raft cohesion; crushed tomato is classical and contributes flavour simultaneously
- 1 litre
- Cold defatted stock — Stock must be cold (below 10 °C) when clearmeat is mixed in, or raft forms prematurely and fails
Method
Combine ground meat, egg whites, finely diced mirepoix, and acid in a mixing bowl. Add a ladleful of the cold stock to loosen, then stir the mixture into the full volume of cold stock in a heavy-bottomed pot. Place over medium heat, stirring constantly and scraping the bottom to prevent scorching, until the mixture reaches approximately 55–60 °C. Stop stirring at this point — the proteins begin to coagulate and must not be disturbed. The raft will rise to the surface and crack naturally. Reduce to the lowest possible simmer and cook without stirring for 45–60 minutes. The liquid beneath the raft should clear progressively. Ladle the finished consommé through the hole in the raft into a fine sieve lined with wet cheesecloth. Do not press or disturb the raft. Season after clarification; never salt before, as salt delays coagulation.
Tips
- Temperature discipline during the early heating phase is everything: keep stirring constantly until 55 °C, then stop completely. Stirring after the raft begins to form will break it into fragments that fall and cloud the stock.
- Stock must be cold when the clearmeat is added; protein begins to denature above 40 °C, so a warm stock will cause premature, uneven coagulation before a cohesive raft can form.
- A natural hole or crack will appear in the centre of the raft — this is the ladle point. Never insert a ladle through the raft's body to extract consommé; always work through this opening.
- Season consommé after clarification, not before: salt depresses the coagulation temperature of egg albumin, weakening the raft.
- A small amount of meat in the clearmeat that is the same type as the stock is essential for flavour depth — the clarification step simultaneously enriches the liquid, not merely filters it.
Variations
- Double consommé
Use finished consommé in place of water to make a secondary stock, then clarify again; intensity doubles; used for aspic and classical banquet service
- White consommé (consommé blanc)
Ground chicken breast + egg whites + leek + celery, no tomato; stock must be pale veal or light chicken to maintain ivory clarity
- Game consommé
Ground pheasant or venison clearmeat with juniper, thyme, and port in the acid component; classical autumn French tasting-menu opener
- Egg white clarification (cheat method)
3 egg whites per litre beaten into cold stock, heat to simmer, skim once raft forms; clarifies partially but cannot equal full clearmeat raft in depth of flavour extraction
- Vegetable consommé
Ground mushroom stems + egg whites + roasted tomato replace meat; requires 1.5× more egg whites (3 per litre) to compensate for lower albumin content
Related ratios
- Classic French stock (fond) ratio
Consommé begins with a well-made fond; the quality of the underlying stock determines the ceiling of the consommé
- Aspic gelatin ratio
Consommé clarified from a collagen-rich stock (4–6g gelatin per 100ml) sets to firm aspic without added gelatin; weaker stocks need 2–4g sheet gelatin per litre
- Cantonese clear broth ratio
The Cantonese clarity-through-temperature approach and the French clearmeat method represent the two major global strategies for achieving brilliantly clear stock

Notes
The physics of the raft
The clearmeat raft functions as a dynamic filter, not merely a physical barrier. As proteins coagulate, they form a loose, sponge-like matrix that actively adsorbs suspended particles through a combination of electrostatic attraction and mechanical trapping. The tomato or other acid in the mixture lowers the pH slightly, accelerating protein denaturation and encouraging tighter raft formation. This is why acid is essential even in non-tomato consommés.
Escoffier's original ratio
In Le Guide Culinaire (1903), Escoffier specifies 250g of lean beef per litre for beef consommé, with 'a few egg whites' as an auxiliary clarifier. Modern culinary school standards have standardised downward to 200g — reflecting improvements in stock-making practices (cleaner starting stocks require less clearmeat) and an emphasis on cost control in professional kitchens.
