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
- Beans
- Provide the main body and starchy texture that becomes creamy and tender when slowly cooked.
- Melted butter
- Adds richness and fat, carrying flavour and giving the cooked beans a smooth mouthfeel.
The step that matters
Cook covered over low heat with minimal water. Gentle, covered cooking lets the beans soften evenly without splitting or drying out. Too much heat can break the skins while the centres stay firm.
Swap the beans
How well each one fits the dish's main ingredients (pepper, butter):
