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 ↓

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
- Peas
- Form the main body and flavour of the puree once cooked and sieved.
- Flour
- Thickens the butter and milk mixture into a smooth base through the roux.
- Butter
- Enriches the roux and adds richness to the finished puree.
- Milk
- Adds creaminess and body, loosening the puree while mellowing its texture.
The step that matters
Passing the mixture through a sieve. Cooked peas hold tough skins and fibres; pressing them through a sieve removes these so the puree turns smooth rather than grainy.
Swap the peas
How well each one fits the dish's main ingredients (flour, milk, onion, pepper, sugar, butter):
- Almondfits better
- Chestnutfits better
- Milletfits better
- Peasthe original
Fit is the average pairing score against flour, milk, onion, pepper, sugar, butter. Candidates are from the same food group and used in at least 100 recipes.
