What ingredient is essential for clarifying consommé with a raft?

• A. Egg whites
• B. Gelatin
• C. Butter
• D. Flour

Answer: (A)

The essential idea is that clearing consommé with a raft relies on proteins in the egg whites to form a raft that traps impurities as the liquid simmers. Egg whites coagulate when heated and rise to the surface, creating a porous barrier that catches solids and emulsified fats, letting the clear liquid pool beneath. This raft is the mechanism that both clarifies and clarifies evenly, producing that bright, pristine consommé. Butter would add fat and gloss but won’t trap particles; flour thickens and can cloud the stock; gelatin can add body but doesn’t create the necessary trapping raft. So egg whites are the crucial ingredient for this method.
