Why it works: Milk and butter 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 ↓

Ingredients
Directions
Make the sauce
Heat the milk in a double boiler until it is ready to boil.
In a separate bowl, mix the flour with the butter to form a paste.
Add the flour paste to the boiling milk and stir to thicken.
Finish
Season with salt and pepper, and add more butter or cream if desired.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Milk
- Forms the liquid base that the flour paste thickens into a cream stock.
- Flour
- Thickens the milk as its starch swells when heated, giving body to the stock.
- Butter
- Adds richness and fat, and helps form the flour paste that thickens the milk.
The step that matters
Adding the flour paste to the boiling milk. Stirring as the paste goes in keeps flour from clumping. Flour starch swells when heated in liquid, so even dispersal gives a smooth, evenly thickened stock.
“What each ingredient does” and “The step that matters” were written by Claude from this recipe’s own method and reviewed in samples by CompKitchen.
