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 ↓

Shared aroma: isobutyraldehyde (malty, green).
Butter and flour barely smell alike, yet cooks put them together in 124,287 recipes: they work on texture and structure more than aroma.

What each ingredient does
- Butter
- Carries flavor and adds richness and a smooth mouthfeel to the sauce.
- All-purpose flour
- Cooked in the hot butter to form a roux that thickens the sauce.
- Boiling water
- Forms the liquid base that the flour roux thickens into a sauce.
The step that matters
Browning the flour without burning. Cooking flour in butter until lightly browned develops a nutty flavor and gives the roux thickening power. If it darkens too far it turns bitter, and if it is not cooked enough the sauce tastes raw and floury.
