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
- Thickens the liquid as its starch swells when heated, giving the sauce body.
- Butter
- Adds richness and a smooth, glossy mouthfeel to the finished sauce.
- Milk
- Forms the main liquid base of the sauce, providing creaminess and body.
The step that matters
Add the flour mixture to the boiling liquid while stirring constantly. Flour lumps form if it meets hot liquid unevenly or is not stirred. Constant stirring disperses the starch so it swells smoothly and the sauce thickens without lumps.
