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 ↓
Egg 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.
Prepare
Preheat the oven to 400°F (200°C).
Beat the eggs very light and separately.
In a bowl, rub together the butter and flour until blended.
Make the base
Add the milk to the butter and flour mixture and cook for 10 minutes.
Stir in the egg yolks, then gently fold in the egg whites.
Season with salt and pepper.
Bake
Pour the mixture into a dish and bake for 20 minutes.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Eggs
- Whites trap air that expands in the oven, lifting the soufflé, while yolks enrich and set the custard.
- Butter
- Adds richness and flavor, and coats the flour so it blends smoothly.
- Flour
- Thickens the milk into a stable base that holds the egg structure.
- Milk
- Provides the liquid that cooks with the flour into a smooth, thick base.
The step that matters
Gently folding in the egg whites. Whited egg foam holds the air that makes the soufflé rise. Stirring or overmixing deflates the foam, so the bake gives a flat, dense result instead of a light one.
