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 ↓

The pairs that carry this dish. Each one is judged two ways: how much their aromas overlap, and how often cooks already put them together.

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
- Young green peas
- Form the main body of the dish, cooked until tender and soft.
- Butter
- Adds richness and moisture, and carries the flour into a smooth coating.
- Flour
- Thickens the butter and helps the sauce cling to the peas.
The step that matters
Cooking the butter-flour mixture. Cooking the flour in melted butter for a few minutes cooks out its raw taste and lets it thicken evenly. Stopping too early can leave a floury flavour and a thin sauce.
Swap the peas
How well each one fits the dish's main ingredients (butter, flour):
- Almondfits better
- Macadamia nutfits better
- Cashew nutfits better
- Peasthe original
Fit is the average pairing score against butter, flour. Candidates are from the same food group and used in at least 100 recipes.
