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 ↓
Melted Butter
Ingredients
Directions
Prepare
Cut the butter into small pieces for easier melting.
In a pint saucepan, combine the butter, flour, and milk. Mix thoroughly and add the water.
Cook
Hold the saucepan over the fire, shaking it gently every minute until it begins to simmer.
Let it stand quietly and boil until it reaches the thickness of good cream.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Butter
- Provides fat and richness, and melts to form the smooth base of the sauce.
- Flour
- Thickens the liquid as its starch swells with heat, giving the sauce body.
- Milk
- Adds moisture and mild flavour, combining with the flour to form a creamy texture.
The step that matters
Shaking gently and bringing to a simmer. Constant gentle shaking keeps the flour evenly dispersed so it does not clump or scorch on the bottom. Thickening happens as starch granules swell in the heated liquid, so the mixture must be moved steadily while heating.
