Why it works: Milk and butter are a kitchen classic. They rank in the top 7% of all ingredient pairs, and 81,283 recipes mention both. Both carry (z)-4-heptenal, which smells biscuit, cream. The science ↓
White Sauce for Vegetables
Ingredients
Directions
The book gives no cooking times; the times in the steps were added in transcription, so check for doneness rather than trusting the clock.
Melt 2 tablespoons of butter in a saucepan over medium heat.
Stir in 2 tablespoons of flour and cook for 1-2 minutes until bubbly.
Gradually whisk in 1 cup of milk and ½ cup of water from boiled vegetables.
Cook, stirring constantly, until the sauce thickens.
Season with salt to taste.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Butter
- Melts to form the fat base that the flour is cooked into.
- Flour
- Thickens the liquid as its starch swells during cooking.
- Milk
- Forms the liquid body of the sauce and adds creaminess.
The step that matters
Gradually whisk in the liquid. Adding the milk and water slowly while whisking keeps the flour dispersed, so the sauce becomes smooth instead of lumpy as the starch hydrates and thickens.
