Why it works: Green beans and onion work together. They rank in the top 13% of all ingredient pairs, and cooks put them together in 334 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
- Green beans
- Form the main body of the salad and provide its tender texture.
- Butter
- Adds richness and fat that carries flavour across the beans.
- Vinegar
- Adds acidity that brightens the dish and balances the butter.
- Onion
- Adds sharp aroma and flavour to the salad.
The step that matters
Boil in salted water until tender. Overcooking softens green beans into a mushy texture, while undercooking leaves them fibrous and raw-tasting. Stop when they are just tender so they keep some bite.
Swap the green beans
How well each one fits the dish's main ingredients (onion, butter, vinegar):
- Mustardfits better
- Chivefits better
- Potatofits better
- Green beansthe original
Fit is the average pairing score against onion, butter, vinegar. Candidates are from the same food group and used in at least 100 recipes.
