Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Egg whites
- Whipped to stiff peaks, they trap air that lifts the soufflé as it cooks.
- Egg yolks
- Add richness and emulsify the base, helping it set smoothly around the air.
- Flour
- Thickens the butter and milk base so it holds the whipped whites.
- Chocolate
- Provides the main flavour and body of the base.
- Butter
- Adds fat and richness to the roux-based base.
The step that matters
Folding the whites into the mixture. Whites deflate quickly when stirred hard. Folding gently keeps the trapped air intact, so the soufflé rises properly when steamed.
