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 ↓

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Tripe
- Forms the main body of the stew and becomes tender during slow simmering.
- Milk
- Forms the cooking liquid and, once thickened, the sauce that coats the dish.
- Flour
- Thickens the milk into a sauce by swelling with heat as it cooks.
- Onions
- Soften during simmering and add sweetness and body to the milk sauce.
- Butter
- Adds richness and a smooth, silky mouthfeel to the sauce.
The step that matters
Thicken the milk with flour. Flour must be stirred in so it dissolves without lumps; it thickens as the milk heats, and clumps form if it is added to hot liquid all at once.
Swap the onion
How well each one fits the dish's main ingredients (flour, butter, milk, pepper):
- Potatofits better
- Capsicumfits better
- Chivefits better
- Onionthe original
Fit is the average pairing score against flour, butter, milk, pepper. Candidates are from the same food group and used in at least 100 recipes.
