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 of the sauce and gives it body and a mild sweetness.
- Flour
- Starch thickens the liquid as it heats, giving the sauce its body.
- Butter
- Adds fat for richness and smoothness in the sauce.
The step that matters
Adding the flour paste to the boiling liquid. Flour must be smoothed into a paste first so it disperses evenly. Added to boiling liquid, its starch swells and thickens the sauce; dumped in dry, it clumps into lumps that are hard to stir out.
