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 ↓

Ingredients
Directions
Make the base
Mix the flour and milk until smooth.
Add the sugar and butter, then heat in a saucepan over medium heat. Stir constantly until it boils and thickens.
Remove from heat and stir in the egg yolks and grated lemon peel.
Bake and serve
Beat the egg whites until stiff, then gently fold into the mixture.
Pour into a well-buttered mold and steam for 30 to 45 minutes.
Serve with boiled custard flavored with lemon.

Flour and butter 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
- Eggs
- Egg whites whipped to stiff peaks trap air, lifting the mixture as it steams.
- Flour
- Thickens the milk base so it holds the folded foam without collapsing.
- Butter
- Adds richness and softness to the base and enriches the texture.
- Milk
- Forms the liquid base that the flour thickens into a smooth sauce.
- Sugar
- Sweetens the base and adds body to the batter.
The step that matters
Folding in the egg whites. Whites beaten until stiff hold the air that makes a soufflé rise. Folding gently preserves that air; stirring or deflating it leaves a dense, flat result.
Swap the lemon

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