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 ↓
Lemon Souffle
Ingredients
Directions
Make the base
Melt the butter in a saucepan.
Stir in the potato starch or Vienna flour and caster sugar.
Add the milk and grated lemon peel, stirring until thickened.
Beat the egg yolks for 30 seconds, then gradually stir into the mixture.
Fold and steam
Fold in the beaten egg whites gently.
Pour the mixture into a buttered pint mold, tying a band of buttered paper around it.
Place the mold in a pot with boiling water, ensuring the water reaches halfway up the mold.
Simmer gently for about 20 minutes, or until firm enough to turn out.
Make the sauce
For the sauce, boil the sugar in cold water for 10 minutes, then add the strained lemon juice.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Egg whites
- Whipped air that lifts and gives the soufflé its light, airy structure.
- Egg yolks
- Enrich the base and help set the custard for a rich, tender texture.
- Potato starch or vienna flour
- Thickens the milk base so it can hold the folded egg whites.
- Butter
- Adds richness and fat to the base for a smooth, tender crumb.
- Milk
- Forms the liquid base that the starch thickens into a custard.
The step that matters
Fold in the egg whites gently. Stirring hard knocks out the air trapped in the whipped whites, so the soufflé rises less and turns out dense.
