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
- String beans
- Form the dish's main body; long simmering softens their fibers until tender.
- Sweet cream
- Adds fat and richness, giving the beans a smooth, creamy coating.
The step that matters
Adding the sweet cream just before serving. Cream held at a long boil can separate and turn grainy or greasy. Stirring it in at the end keeps it smooth and evenly coating the beans.
Swap the beans
How well each one fits the dish's main ingredients (pepper, cream):
- Chestnutfits about as well
- Pistachiofits about as well
- Beansthe original
- Walnutfits about as well
Fit is the average pairing score against pepper, cream. Candidates are from the same food group and used in at least 100 recipes.
