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 ↓
White Sauce
Ingredients
Directions
Prepare
Scald the cream in a saucepan.
Melt the butter in a separate pan until bubbling.
Make the sauce
Add the cornstarch (or flour) to the butter and stir quickly until well mixed.
Gradually beat in one-third of the milk, then the second third, and finally the last third.
Cook the mixture, stirring constantly, until it is smooth and thick.
Finish
Let it cool slightly before adding to any fish or meat.

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
- Adds richness and flavor, and its fat coats starch granules to help keep the sauce smooth.
- Cornstarch
- Swells and thickens when heated in liquid, giving the sauce its body.
- Cream
- Adds richness and body, giving the sauce a silky mouthfeel.
- Milk
- Supplies the liquid that the thickener hydrates to form the sauce.
The step that matters
Gradually beating in the milk. Starch granules clump when they meet a large amount of liquid at once. Adding the milk in thirds while beating keeps the starch dispersed, so the sauce cooks up smooth rather than lumpy.
