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 dish and provide its vegetable flavour and bulk.
- Milk
- Adds moisture and creaminess to the sauce.
- Butter
- Adds fat for richness and a smooth mouthfeel.
- Flour
- Thickens the milk as it cooks, giving the sauce body.
The step that matters
Cook the sauce until thickened. Flour needs sustained heat and stirring to swell and gelatinise its starch. Stopping early leaves a thin, raw-tasting sauce, while overcooking can cause scorching on the base of the pot.
Swap the peas
How well each one fits the dish's main ingredients (milk, butter, pepper, flour):
- Almondfits better
- Chestnutfits better
- Milletfits better
- Peasthe original
Fit is the average pairing score against milk, butter, pepper, flour. Candidates are from the same food group and used in at least 100 recipes.
