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 ↓
Drawn-butter Sauce
Ingredients
Directions
In a saucepan, melt the butter over low heat.
Add the flour and stir until combined.
Gradually add the boiling water while shaking the saucepan continuously.
Allow the sauce to simmer gently until it thickens, but do not let it boil.

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.
Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Butter
- Provides the fat base, rich flavor and smooth mouthfeel of the sauce.
- All-purpose flour
- Its starch thickens the sauce as it heats in the liquid and fat.
- Boiling water
- Forms the liquid of the sauce and hydrates the flour so it thickens evenly.
The step that matters
Simmer gently without boiling. Flour starch thickens as it heats, but a hard boil can break the butter and water emulsion, leaving the sauce greasy and grainy.
