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
- Butter
- Enriches the broth with fat and helps the flour cook into a smooth base.
- Flour
- Cooked with butter to form a roux that thickens the broth.
- Jelly-stock
- Forms the savoury liquid base of the broth.
- Milk
- Adds creaminess and mild sweetness to the finished broth.
The step that matters
Cook the flour and butter for five minutes. Flour must cook in fat long enough to lose its raw taste and thicken evenly. Adding spoonfuls of soup while cooking keeps the roux from browning and turning lumpy or dark, which would change the colour and flavour of the white broth.
