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
- Fat that carries flavor and gives the sauce a rich, smooth body.
- Flour
- Starch that thickens the milk into a sauce as it cooks.
- Milk
- Liquid base that becomes the creamy sauce once thickened.
The step that matters
Cook until there is no taste of raw starch. Raw flour tastes pasty, and its starch only thickens fully when heated. Stirring while adding the milk prevents lumps, and cooking long enough gives a smooth, well-set sauce.
