Why it works: Green beans and pepper work together. They rank in the top 13% of all ingredient pairs, and cooks put them together in 369 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 dish and provide the tender-crisp texture.
- Butter
- Browning produces nutty, toasted flavour and adds richness to the beans.
- Vinegar
- Adds acidity that brightens the rich, buttery flavour.
The step that matters
Browning the butter. Melted butter turns brown as its milk solids toast, giving nutty flavour. Heating too long or too hot burns the solids and makes the butter bitter, so watch it closely and remove it once it reaches a deep amber.
Swap the green beans
How well each one fits the dish's main ingredients (pepper, butter, vinegar):
- Capsicumfits better
- Mustardfits better
- Cabbagefits better
- Green beansthe original
Fit is the average pairing score against pepper, butter, vinegar. Candidates are from the same food group and used in at least 100 recipes.
