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
- Milk
- Forms the liquid base that thickens into the sauce's body.
- Cornstarch or white flour
- Thickens the milk as its starch swells when heated, giving the sauce body.
- Butter
- Adds richness and smooth mouthfeel, and coats the starch so it blends without lumps.
The step that matters
Cooking until thickened. Starch granules must be heated to swelling temperature while stirred constantly; otherwise they settle and clump, leaving lumps and a thin, floury sauce.
