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 moderately hot oven”. The 350°F (175°C) in the steps is the modern equivalent, not the book's own figure.
Make the base
In a saucepan, rub together the butter and flour over medium heat until bubbling.
Gradually add the hot milk, seasoning with pepper and coarse sea salt.
Slowly stir in the grated cheese and remove from heat.
Combine and bake
Add the beaten egg yolks and cool the mixture.
Gently fold in the beaten egg whites until well combined.
Pour the mixture into a well-buttered pudding dish.
Bake in a preheated oven at 350°F (175°C) for 15 to 20 minutes, until set like custard.
Serve immediately.

Flour and butter 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
- Eggs
- Egg whites trapped in the mixture expand in the oven and set the soufflé into a light, airy structure.
- Flour
- Cooked with butter, it forms a roux that thickens the milk into a smooth, stable base.
- Milk
- Forms the liquid base that the roux thickens and the cheese is stirred into.
- Cheese
- Adds rich flavour and fat to the base, giving the soufflé its savoury character.
- Butter
- Enriches the roux with fat and flavour, and greases the dish to help the soufflé release.
The step that matters
Gently fold in the beaten egg whites. Egg whites hold air only while intact. Vigorous stirring knocks out the trapped air, so the soufflé rises less and turns dense. Fold gently to keep the bubbles.
