Why it works: Butter and lemon are a kitchen classic. They rank in the top 16% of all ingredient pairs, and cooks put them together in 41,227 recipes. Both carry 3-hexenal, which smells apple, fruity. The science ↓
Lemon Souffle
Ingredients
Directions
Make the base
In a saucepan, combine the butter, 2 oz. sugar, lemon juice, grated rind of 1 lemon, and the beaten yolks of 4 eggs.
Stir over low heat until the mixture thickens to the consistency of thick cream, but do not let it boil.
Steam and finish
Add the stiffly beaten egg whites and mix gently.
Steam the mixture for 16 minutes.
Once cooled, cover the soufflé with slightly beaten cream and decorate as desired.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Eggs
- Yolks thicken the base, and whites whipped stiff add lift and airy structure.
- Butter
- Adds fat for richness and a smooth, tender texture.
- Gelatine
- Sets the mixture so it holds its shape when cool.
- Lemons
- Juice gives sharp acidity and the grated rind adds fresh aroma.
- Sugar
- Sweetens the base and balances the lemon's tartness.
The step that matters
Thicken the base over low heat without boiling. Egg yolks thicken gently at moderate heat. If the mixture boils, the yolks scramble, leaving lumps and a grainy texture instead of a smooth, thick base.
Swap the lemon

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