Why it works: Beans and olive match in chemistry and in kitchens. They rank in the top 5% of all ingredient pairs, and cooks put them together in 3,470 recipes. Both carry trans,trans-2,4-nonadienal, which smells fatty, green. The science ↓
Bean Salad
Ingredients
Directions
Prepare and cook
String the young beans and break them into half-inch pieces or leave them whole, then wash them.
Cook the beans in salted water until soft, then drain well.
Dress the salad
Add finely chopped onions, pepper, salt, and vinegar to the beans.
Once cool, add olive oil or melted butter.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Young beans
- Form the body of the salad, becoming tender when cooked and holding their shape.
- Finely chopped onions
- Add sharp aroma and savory flavor that stands out against the mild beans.
- Vinegar
- Adds acidity that brightens the flavor and cuts the richness of the fat.
- Olive oil or melted butter
- Adds fat and smooth mouthfeel, carrying flavor across the beans.
The step that matters
Drain the beans well, then add the fat once they have cooled. Leftover cooking water dilutes the vinegar and dressing, so the beans taste flat. Fat added to very hot beans can separate or pool; once cool, it clings more evenly to the beans.
Swap the beans
How well each one fits the dish's main ingredients (onion, pepper, vinegar, olive):
- Sesamefits better
- Black-eyed peafits about as well
- Beansthe original
- Chickpeafits about as well
Fit is the average pairing score against onion, pepper, vinegar, olive. Candidates are from the same food group and used in at least 100 recipes.
