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 ↓
Pea Souffle
Ingredients
Directions
Prepare the pea base
Boil the peas until very soft and mash through a colander.
Add melted butter and milk mixed with beaten egg yolks to the pea pulp.
Season with salt and pepper, and mix thoroughly.
Fold and bake
Beat the egg whites until stiff and fold into the mixture.
Pour into a buttered dish, cover, and bake for 20 minutes.
To brown, remove the cover and return to the oven for a few minutes.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Eggs
- Whipped whites trap air for a light, risen structure, while yolks enrich the custard and help it set.
- Peas
- Mashed cooked peas form the bulk of the body and provide the main flavour and moisture.
- Milk
- Adds liquid and softness, helping the mixture stay tender as it bakes.
- Butter
- Adds richness and fat, giving a smoother, more tender texture.
The step that matters
Fold in the egg whites. Stiffly beaten whites hold the air that makes a soufflé rise. Folding gently, rather than stirring, keeps that air from collapsing before the dish reaches the oven.
Swap the peas
How well each one fits the dish's main ingredients (butter, milk, egg, pepper):
- Walnutfits about as well
- Cocoafits about as well
- Peasthe original
- Almondfits about as well
Fit is the average pairing score against butter, milk, egg, pepper. Candidates are from the same food group and used in at least 100 recipes.
