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
- Green lima beans
- Provide the main body of the dish and tender texture when simmered.
- Butter
- Adds richness and fat, carrying flavor through the beans and sauce.
- Flour
- Thickens the liquid into a smooth, lightly bound sauce when cooked with butter.
- Water, meat stock, or milk
- Forms the liquid of the sauce, giving moisture and body once simmered.
The step that matters
Stir the flour into the butter until smooth and frothy. Cooking flour in melted butter first, as a roux, removes raw starch taste and lets it thicken evenly. Adding liquid before the flour is well blended can leave lumps.
Swap the lima beans
How well each one fits the dish's main ingredients (butter, flour, meat):
- Almondfits better
- Walnutfits better
- Pistachiofits better
- Lima beansthe original
Fit is the average pairing score against butter, flour, meat. Candidates are from the same food group and used in at least 100 recipes.
