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 ↓

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
- Adds richness and flavor, and melts into the sauce to give it a smooth, fatty body.
- Flour
- Thickens the sauce as its starch swells in the liquid when heated.
The step that matters
Stir continuously over medium heat. Flour can clump and scorch on the bottom of the pan if it is left unstirred. Constant stirring spreads the starch evenly so the sauce thickens smoothly.
