Why it works: Milk and flour are a kitchen classic. They rank in the top 14% of all ingredient pairs, and cooks put them together in 78,219 recipes. Both carry isobutyraldehyde, which smells malty, green. The science ↓

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Milk
- Forms the base of the sauce, giving it liquid and body once thickened.
- Cream
- Adds richness and a smoother, fuller mouthfeel to the sauce.
- Flour
- Thickens the sauce as its starch swells in the hot liquid.
- Egg whites
- Whipped to stiff foam, they make the mixture light and airy.
The step that matters
Folding the sauce into the beaten egg whites. Stirring constantly while pouring in the hot sauce keeps the foam light. Adding it too fast or without stirring can deflate the whites and cook them unevenly.
