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 ↓
Canned String-beans
Ingredients
Directions
Prepare
Cut the canned string beans into neat lengths.
Cook and serve
Cook the beans in their own liquid for 30 minutes or until very tender.
Stir in 1 tablespoon of butter, salt, and pepper when almost done.
Simmer for an additional 10 minutes.
Drain off the liquid and serve the beans on a hot dish with a bit of butter on top.
If there isn't enough liquid to cover the beans, add a little cold water while cooking.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Canned string beans
- Main ingredient; long simmering softens their fibres until they become tender.
- Butter
- Adds fat and richness, giving the beans a smoother flavour and mouthfeel.
The step that matters
Keep the beans covered in liquid while cooking. Beans cooked partly out of liquid can dry out and heat unevenly. Keeping them submerged lets them soften uniformly during the long simmer, which is why the record advises adding cold water when the liquid runs low.
Swap the beans
How well each one fits the dish's main ingredients (butter, pepper):
- Walnutfits about as well
- Black-eyed peafits about as well
- Almondfits about as well
- Beansthe original
Fit is the average pairing score against butter, pepper. Candidates are from the same food group and used in at least 100 recipes.
