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 ↓

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Green peas
- Form the main body of the soup, and their starch thickens it as they cook and mash.
- Milk
- Adds liquid and softness, mellowing the pea flavor into a smoother soup.
- Cream
- Adds fat for a richer, silkier mouthfeel.
- Butter
- Adds fat and richness, rounding out the flavor and smoothing the texture.
The step that matters
Boil the peas until fully tender before mashing. Peas that are only partly cooked keep firm starch and cell walls, so they mash unevenly and strain poorly through the colander. Fully softened peas break down into a smooth pulp that gives the soup an even body.
Swap the peas
How well each one fits the dish's main ingredients (milk, cream, butter, egg, pepper):
- Almondfits better
- Walnutfits better
- Pecansfits about as well
- Peasthe original
Fit is the average pairing score against milk, cream, butter, egg, pepper. Candidates are from the same food group and used in at least 100 recipes.
