Why it works: Beans and pepper are a kitchen classic. They rank in the top 11% of all ingredient pairs, and cooks put them together in 4,733 recipes. Both carry 2-isopropyl-3-methoxypyrazine, which smells earthy, pea. The science ↓

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- French beans
- Form the main body of the dish and provide its fresh, green vegetable texture when cooked until tender.
- Butter
- Adds fat and richness, coating the beans and giving them a smooth, savory flavor.
The step that matters
Boil the beans until tender. Boiling in salted water seasons the beans from within and softens them evenly. Overcooking turns them dull and mushy, while undercooking leaves them tough and fibrous.
Swap the beans
How well each one fits the dish's main ingredients (butter, pepper):
- Walnutfits about as well

Fit is the average pairing score against butter, pepper. Candidates are from the same food group and used in at least 100 recipes.
