Why it works: Butter and bread are a kitchen classic. They rank in the top 7% of all ingredient pairs, and cooks put them together in 27,232 recipes. Both carry delta-decalactone, which smells sweet, creamy. The science ↓
Cheese 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
Boil the bread and milk together, stirring until smooth.
Add the cheese and butter, stirring over heat for 1 minute.
Remove from heat and add mustard, seasoning, and egg yolks.
Bake
Beat the egg whites to stiff peaks and gently fold them into the mixture.
Pour into a greased baking dish and bake for 15 minutes at 400°F (200°C).

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Egg whites
- Whipped to stiff peaks, they trap air and make the soufflé rise and turn light.
- Egg yolks
- Add richness and emulsify the base, helping it set into a tender custard structure.
- Bread
- Boiled with milk to form a thickened base that gives the soufflé body and structure.
- Cheese
- Adds savory flavor and fat, enriching the base as it melts into the mixture.
- Butter
- Adds fat and richness to the base, improving flavor and tenderness.
The step that matters
Fold the egg whites gently. Stiff egg whites hold air that makes the soufflé rise. Overmixing deflates the foam, so the soufflé bakes flat and dense.
Swap the mustard
How well each one fits the dish's main ingredients (cheese, milk, egg, butter, bread, pepper):
- Capsicumfits better
- Potatofits better
- Asparagusfits better

Fit is the average pairing score against cheese, milk, egg, butter, bread, pepper. Candidates are from the same food group and used in at least 100 recipes.
