Why it works: Butter and cream are a kitchen classic. They rank in the top 8% of all ingredient pairs, and cooks put them together in 41,516 recipes. Both carry delta-dodecalactone, which smells sweet, creamy. The science ↓
Mocha Souffle
Ingredients
Directions
The book gives no oven temperature. The 400°F (200°C) in the steps was added when the recipe was transcribed, as a starting point.
Make the base
Melt the butter in a saucepan.
Add the flour and stir to combine.
Gradually pour in the hot coffee and cream, stirring until smooth.
Add the salt and sugar, then mix in the beaten egg yolks.
Cook over hot water until the mixture is smooth.
Fold and bake
Remove from heat and gently fold in the stiffly beaten egg whites.
Add the vanilla and mix gently.
Pour the mixture into a buttered baking dish.
Bake in a water bath at 400°F (200°C) for 25 minutes.
Serve with Mocha sauce.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Egg whites
- Whipped and folded in, they trap air and make the soufflé rise and turn light.
- Egg yolks
- Mixed into the base, they add richness and help set the custard-like structure.
- Flour
- Cooked with the butter, it thickens the base so it can hold the whipped whites.
- Butter
- Melted with the flour to form a roux that gives the base body and richness.
- Sugar
- Adds sweetness and balances the bitterness of the coffee and cocoa notes.
The step that matters
Folding in the egg whites. Whites must be stiffly beaten and folded gently so the air they hold is not lost; deflating the mixture prevents the soufflé from rising properly.
“What each ingredient does” and “The step that matters” were written by Claude from this recipe’s own method and reviewed in samples by CompKitchen.
