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
Use a pint stewpan reserved for this purpose.
Cut the butter into small pieces for easier melting.
Cook the sauce
Add the butter, flour, and milk to the stewpan and mix well.
Gradually add the water while holding the pan over the fire.
Shake the pan continuously until the mixture just boils.
The final consistency should be similar to good cream.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Butter
- Fat that carries flavour and gives the sauce a smooth, rich mouthfeel.
- Flour
- Starch that thickens the liquid as it heats with the butter and milk.
- Milk
- Adds milk proteins and sugars for body and a creamier texture.
The step that matters
Shaking the pan until it just boils. Flour must be evenly dispersed in the liquid and heated so its starch swells and thickens. Continuous shaking keeps the mixture moving, which helps prevent lumps and scorching at the base of the pan.
