Why it works: Milk and butter 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 ↓
Pea Souffle
Ingredients
Directions
Prepare the base
Strain the peas and combine with enough milk to make 1 pint.
In a saucepan, melt the butter and stir in the flour to create a roux.
Gradually add the strained peas and milk mixture to the roux, stirring continuously.
Season with salt, pepper, sugar, and onion juice if desired.
Finish and cook
Fold in the well-beaten egg whites gently.
Pour the mixture into buttered molds.
Steam or bake in a water bath until the center is firm.
Turn out of the molds before serving.

Butter and flour 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
- Egg whites
- Whipped egg whites trap air and set into a light, airy structure when cooked.
- Flour
- Forms a roux with butter that thickens the pea and milk mixture into a smooth base.
- Butter
- Enriches the roux and adds richness and flavour to the base.
- Milk
- Adds liquid and body to the pea purée, giving a softer, creamier texture.
- Peas
- Provide the main flavour and colour of the soufflé.
The step that matters
Fold in the egg whites gently. Whipped egg whites hold the air that makes a soufflé rise. Heavy stirring deflates the foam, so the mixture cooks dense rather than light and airy.
Swap the onion
The recipe marks onion as optional. How well each one fits the dish's main ingredients (peas, milk, butter, flour, pepper, sugar, egg):
- Asparagusfits better
- Capsicumfits better
- Sweet potatofits better
- Onionthe original
Fit is the average pairing score against peas, milk, butter, flour, pepper, sugar, egg. Candidates are from the same food group and used in at least 100 recipes.
