Why it works: Butter and flour are a kitchen classic. They rank in the top 12% of all ingredient pairs, and cooks put them together in 124,287 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
- Sugar
- Adds sweetness and body to the sauce.
- Butter
- Adds fat for richness and a smooth, silky texture.
- Flour
- Thickens the sauce as its starch swells in the hot liquid.
- Eggs
- Yolks enrich and thicken the sauce, while whites add lightness when folded in.
The step that matters
Fold in the beaten egg whites last. Beaten whites hold air that makes the sauce light. Folding gently, rather than stirring, keeps that air from deflating, so the sauce stays delicate when served.
“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.
