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
- Flour
- Starch that thickens the milk into a smooth sauce as it cooks.
- Butter
- Fat that carries flavor and combines with flour to form a roux.
- Milk
- Liquid that hydrates the starch and forms the body of the sauce.
The step that matters
Adding the milk slowly while stirring constantly. Adding liquid gradually while stirring keeps the flour dispersed, so the sauce thickens smoothly without lumps.
