Why it works: Milk and butter 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 moderate oven”. The 350°F in the steps is the modern equivalent, not the book's own figure.
Make the base
Heat the milk in a double boiler.
Beat the butter until creamy, then mix in the flour.
Gradually pour the hot milk into the butter-flour mixture, stirring constantly.
Return to the heat and cook for 6 minutes.
Add the chocolate and eggs
In a small pan, combine the chocolate, sugar, and 2 tablespoons of water; stir over heat until smooth.
Mix the chocolate mixture into the double boiler mixture.
Remove from heat and stir in the beaten egg yolks; let cool.
Once cool, fold in the beaten egg whites until stiff.
Bake and serve
Pour the batter into a well-buttered dish and bake in a moderate oven (350°F) for 22 minutes.
Serve immediately with vanilla cream sauce.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Eggs
- Yolks enrich and set the base, while whipped whites provide the airy lift.
- Flour
- Starch thickens the butter and milk mixture so it can hold the batter's structure.
- Milk
- Liquid that gelatinises the flour paste and adds moisture to the batter.
- Chocolate
- Supplies the main flavour and fat, and helps the batter set as it bakes.
- Butter
- Adds richness and flavour to the base and helps grease the dish for release.
- Sugar
- Sweetens the chocolate mixture and balances its bitterness.
The step that matters
Fold in the egg whites. Whites hold air only when whipped stiff, and a hot or heavy base deflates them. Folding gently, after the base has cooled, keeps the batter light so the soufflé rises.
