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
- Butter
- Adds fat and richness, and carries flavor through the sauce.
- Milk
- Forms the liquid base that the flour starch swells in to thicken the sauce.
- Flour
- Its starch swells and thickens the hot liquid, giving the sauce body.
The step that matters
Cook over medium heat, stirring constantly, until the sauce thickens.. Flour starch only thickens fully when heated in liquid. Constant stirring spreads the flour evenly, preventing lumps, and keeps the sauce from scorching on the base of the pan.
