Why it works: Butter and milk are a kitchen classic. They rank in the top 7% of all ingredient pairs, and cooks put them together in 81,283 recipes. Both carry (z)-4-heptenal, which smells biscuit, cream. The science ↓
Chocolate Souffle
Ingredients
Directions
The book says “a quick oven”. The 400°F (200°C) in the steps is the modern equivalent, not the book's own figure.
Make the base
Heat the butter in a saucepan to make a roux.
Stir in the flour and thin with the scalding milk as it thickens.
Cook the mixture for 2 minutes.
Combine the thickened milk with the beaten egg yolks and sugar.
Beat the mixture for 1 minute.
Add the grated chocolate and beat until the mixture cools.
Cover the mixture to prevent hardening.
Bake and serve
Bake in a 400°F (200°C) oven for 30 minutes.
Serve immediately with whipped cream.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Egg yolks
- Enrich the base and help the soufflé set and turn rich when baked.
- Flour
- Thickens the butter and milk into a roux that gives the base body and structure.
- Butter
- Fat that forms the roux with the flour and adds richness.
- Grated chocolate
- Provides the main flavour and adds richness to the base.
- Milk
- Liquid that is thickened with the roux to form the soufflé base.
The step that matters
Cover the mixture to prevent hardening. A cooled base with a skin can stiffen and lose its smooth, airy texture, so covering it keeps the mixture soft and workable before baking.
