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 ↓

Butter and flour barely smell alike, yet cooks put them together in 124,287 recipes: they work on texture and structure more than aroma.
Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Macaroni
- Forms the bulk of the dish and carries the sauce.
- Butter
- Adds richness and forms the fat base of the roux.
- Milk
- Liquid that, thickened with the roux, becomes the smooth sauce.
- Flour
- Thickens the sauce when cooked with butter to form a roux.
The step that matters
Adding the milk to the roux. Adding cold or fast-poured milk can clump the flour into lumps. Adding the milk gradually while stirring constantly lets the starch disperse evenly and thicken into a smooth sauce.
“What each ingredient does” and “The step that matters” were written by Claude from this recipe’s own method and reviewed in samples by CompKitchen.
