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
- Provide the main flavour, colour and body of the puree once strained.
- Milk
- Adds moisture and creaminess to the peas and the sauce.
- Butter
- Adds fat for richness and a smooth mouthfeel.
- Flour
- Thickens the mixture as its starch swells when cooked in the melted butter.
The step that matters
Gradually mix in the hot milk and pea pulp. Flour must be stirred into melted butter first so each starch granule is coated by fat. Adding the liquid slowly while stirring lets the starch disperse evenly, which prevents lumps and gives a smooth, even thickness.
Swap the peas
How well each one fits the dish's main ingredients (milk, butter, flour):
- Almondfits better
- Pistachiofits better
- Chestnutfits better
- Peasthe original
Fit is the average pairing score against milk, butter, flour. Candidates are from the same food group and used in at least 100 recipes.
