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
In a saucepan, heat the butter to make a roux.
Stir in the flour and gradually add the scalding milk as it thickens.
Cook for 2 minutes.
Beat the egg yolks and sugar together until light.
Stir the thickened milk into the egg mixture and beat for 1 minute.
Add the grated chocolate and beat until the mixture cools.
Cover and set aside until cold.
Bake and serve
Bake in a preheated oven at 400°F (200°C) 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
- Add richness and help set the mixture into a light, custardy structure when baked.
- Flour
- Thickens the milk into a roux that gives the base body and holds the soufflé's structure.
- Milk
- Forms the liquid base that the roux thickens and that the yolks enrich.
- Grated chocolate
- Adds flavor and fat, giving the base a rich, dense character.
- Sugar
- Sweetens the base and helps the yolks whip to a light, stable texture.
The step that matters
Let the base cool before folding in the whites. A base that is too hot can deflate or cook the egg yolks, and a cold base keeps the air in later whipped whites for a higher rise. Here, the record says to beat the chocolate in until the mixture cools and then chill it until cold.
