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 ↓
Apple Soufflee
Ingredients
Directions
Prepare the apples
Pare and core the apples, then stew them with sugar and water until tender.
Rub the apples through a sieve to obtain ½ pound of pulp.
Make the soufflé
Mix the pulp with flour, lemon rind, butter, and milk, stirring over heat until thickened.
Add the yolks of 2 eggs and 1 whole egg to the hot mixture.
Whip the whites of the 2 eggs to stiff peaks and gently fold into the mixture.
Steam and serve
Steam in a well buttered mold for 30 minutes.
Serve with cream or boiled custard.

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
- Apples
- Provide the main body and fruity flavour of the soufflé once pureed into pulp.
- Flour
- Thickens the pulp into a stable base that holds the risen eggs.
- Eggs
- Yolks enrich and set the base, while whipped whites lift the mixture as it steams.
- Butter
- Adds richness and a tender texture, and greases the mold to prevent sticking.
- Milk
- Adds moisture and softens the starch-thickened base for a smooth texture.
- Sugar
- Sweetens the apples and balances the tartness of the fruit.
The step that matters
Folding in the whipped egg whites. Fold gently so the air in the stiff whites is kept. That trapped air expands during steaming and makes the soufflé rise; overmixing deflates it and leaves it dense.
Swap the apple
How well each one fits the dish's main ingredients (sugar, flour, lemon, butter, milk, egg):
- Vanillafits better
- Raisinfits better
- Figfits better
- Applethe original
Fit is the average pairing score against sugar, flour, lemon, butter, milk, egg. Candidates are from the same food group and used in at least 100 recipes.
