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
- Mussels
- Form the main body of the dish and become tender when gently stewed.
- Butter
- Adds richness and fat, and blends with flour to form a thickening base.
- Flour
- Thickens the saved liquor into a smooth sauce when cooked with butter.
The step that matters
Thicken with butter and flour, then stew gently. Flour must be cooked with the butter and liquid so its starch swells and thickens evenly. Boiling too hard or leaving it unstirred can cause lumps or a thin, pasty texture.
Swap the mace
How well each one fits the dish's main ingredients (butter, flour):
- Jalapenofits better
- Capersfits better
- Nutmegfits better
- Macethe original
Fit is the average pairing score against butter, flour. Candidates are from the same food group and used in at least 100 recipes.
