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
- Flour
- Starch from the flour swells in hot liquid, thickening the sauce.
- Butter
- Fat that coats the flour, adding richness and a smooth, silky mouthfeel.
- Milk
- Liquid base that the flour starch thickens into a pourable sauce.
The step that matters
Stir constantly while thickening. Flour starch swells and thickens as the sauce heats. Constant stirring spreads heat evenly and keeps starch from clumping or scorching on the base of the pan.
