Why it works: Beans and mustard match in chemistry and in kitchens. They rank in the top 4% of all ingredient pairs, and cooks put them together in 852 recipes. Both carry 2-isopropyl-3-methoxypyrazine, which smells earthy, pea. The science ↓
Bean Salad
Ingredients
Directions
Cook the beans
String the yellow wax beans and boil them whole until tender.
Remove the beans and place them on a clean cloth to cool.
Once cooled, transfer the beans to a salad dish.
Dress and serve
In a bowl, mix olive oil, salt, pepper, and mustard.
Add cider vinegar to the mixture and stir well.
Pour the dressing over the beans and toss gently.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Yellow wax beans
- Provide the main body and texture of the salad.
- Olive oil
- Carries flavor and gives the dressing a smooth, rich body.
- Prepared mustard
- Emulsifies the dressing so the oil and vinegar hold together better.
- Cider vinegar
- Adds acidity that brightens the dressing and balances the oil.
The step that matters
Cool the beans before dressing. Warm beans absorb dressing unevenly and can turn soft or watery. Cooling them on a clean cloth lets surface moisture evaporate so the oil-and-vinegar dressing clings and seasons the beans well.
Swap the beans
How well each one fits the dish's main ingredients (olive, pepper, mustard, cider, vinegar):
- Beansthe original
- Black-eyed peafits about as well
- Chickpeafits about as well
- Sesamefits about as well
Fit is the average pairing score against olive, pepper, mustard, cider, vinegar. Candidates are from the same food group and used in at least 100 recipes.
