Why it works: Flour and milk are a kitchen classic. They rank in the top 14% of all ingredient pairs, and cooks put them together in 78,219 recipes. Both carry isobutyraldehyde, which smells malty, green. The science ↓

Ingredients
Directions
In a saucepan, heat the reserved fat over medium heat.

Gradually add the boiling water or fresh milk, stirring until thickened.
Season with salt and pepper to taste, then strain through a sieve.

Flour and milk barely smell alike, yet cooks put them together in 78,219 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
- Reserved fat
- Carries flavour and coats the flour so it cooks into a smooth roux.
- Flour
- Thickens the liquid once cooked in fat and whisked into it, giving the gravy body.
- Boiling water or fresh milk
- Forms the liquid that the roux thickens into a pourable gravy.
The step that matters
Cook the flour in the fat before adding liquid. Stirring the flour into the hot fat until it forms a paste cooks out its raw taste and lets it disperse. Adding liquid too early or too fast can leave lumps, so add the liquid gradually while stirring.
