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 ↓

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Eggs
- Yolks thicken the custard while whites, beaten stiff, lift the soufflé as it bakes.
- Flour
- Thickens the milk mixture into a stable base that holds the risen structure.
- Butter
- Enriches the base and adds fat for a tender texture.
- Milk
- Forms the liquid base that flour thickens into the custard.
- Sugar
- Adds sweetness and balances the richness of the custard.
The step that matters
Fold in the egg whites. Beaten whites trap air that makes the soufflé rise. Folding gently keeps that air in, while stirring hard deflates the mixture and leads to a flat result.
