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 ↓
Cheese Souffle
Ingredients
Directions
The book says “a hot oven”. The 400°F (200°C) in the steps is the modern equivalent, not the book's own figure.
Prepare
Preheat the oven to 400°F (200°C).
Grease a soufflé dish with clarified butter and wrap a well‑buttered piece of paper around it for support.
Make the base
Melt the butter in a saucepan, stir in the flour, then add the milk and bring to a boil.
Remove from heat, mix in the egg yolks, then stir in the cheese and season with cayenne and salt.
Bake and serve
Whisk the egg whites until stiff, then gently fold them into the cheese mixture.
Pour the mixture into the prepared soufflé dish and bake for 25 to 30 minutes.
Serve immediately in the dish, optionally wrapped in a warmed napkin.

Butter and flour barely smell alike, yet cooks put them together in 124,287 recipes: they work on texture and structure more than aroma.
Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Egg whites
- Whisked to stiffness, they trap air that lifts the soufflé as it bakes.
- Egg yolks
- Enrich the base and add richness and structure as they set with heat.
- Flour
- Thickens the butter and milk into a sauce base that holds the air and cheese.
- Parmesan cheese
- Adds savory, salty flavor and body to the base.
- Milk
- Forms the liquid of the thickened base, giving a smooth, creamy texture.
The step that matters
Folding in the egg whites. Stiffly whisked whites hold the air that makes the soufflé rise. Folding gently keeps that air from collapsing, so the soufflé stays light and tall in the oven.
“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.
