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 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 small saucepan, melt the butter and mix in the flour over medium heat.
Add the milk and stir until the mixture boils and thickens.
Remove from heat and stir in the salt, cayenne, white pepper, cheese, and egg yolks one at a time.
Fold and bake
Beat the egg whites until stiff and gently fold them into the mixture.
Pour the mixture into a buttered pie dish and bake at 400°F (200°C) for 20 minutes.
Serve immediately.

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 into foam, they trap air that lifts and gives the souffle its light structure.
- Flour
- Thickens the melted butter and milk into a smooth base that holds the mixture together.
- Milk
- Forms the liquid base that the flour thickens into a white sauce.
- Cheese
- Adds savory flavor and richness to the base.
- Egg yolks
- Enrich the base and add richness and body to the finished souffle.
The step that matters
Fold in the egg whites gently. The whipped whites hold the air that makes the souffle rise. Stirring them vigorously deflates the foam, so the souffle bakes up flat and dense instead of light.
Swap the white pepper
How well each one fits the dish's main ingredients (butter, flour, milk, cheese, egg, pepper):
- Nutmegfits better
- Parsleyfits better
- Cinnamonfits better
- White pepperthe original
Fit is the average pairing score against butter, flour, milk, cheese, egg, pepper. Candidates are from the same food group and used in at least 100 recipes.
