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 moderate oven”. The 350°F (175°C) in the steps is the modern equivalent, not the book's own figure.
Make the base
Melt the butter in a saucepan over medium heat.
Stir in the flour, salt, and cayenne until combined.
Gradually add the scalded milk, stirring until smooth and thick.
Remove from heat and stir in the grated cheese.
Allow the mixture to cool slightly, then add the beaten egg yolks.
Fold and bake
In a separate bowl, whip the egg whites to stiff peaks.
Gently fold the egg whites into the cheese mixture.
Pour the mixture into a buttered baking dish.
Bake in a preheated oven at 350°F (175°C) for about 20 minutes.

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
- Whipped to stiff peaks, they trap air and make the soufflé rise and turn light.
- Egg yolks
- Enrich the base and help it set into a rich, custardy structure as it bakes.
- Flour
- Thickens the butter and milk into a smooth white sauce that holds the air bubbles.
- Grated cheese
- Adds rich flavour and fat, and gives the soufflé its savoury character.
- Milk
- Forms the liquid base of the white sauce, adding moisture and a soft texture.
The step that matters
Gently fold the egg whites into the cheese mixture. Folding keeps the air trapped in the whipped whites. Stirring or beating vigorously deflates the foam, so the soufflé bakes flat and dense instead of rising.
