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
- Eggs
- Add body and richness, and set firmly when boiled.
- Butter
- Adds fat and richness, giving the sauce a smooth, rounded mouthfeel.
- Baked flour
- Acts as the thickener, as its starch swells in the hot liquid to thicken the sauce.
The step that matters
Stir the mixture into the boiling water. Flour clumps when it meets hot liquid without preparation. Kneading it with butter first coats the starch granules with fat, so they separate and disperse evenly as the sauce thickens.
“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.
