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 ↓

Ingredients
Directions
Prepare
Cut off the fibers from both sides of the string beans and clip them into short pieces.
Boil the beans in hot salted water until tender, then drain them well.
Make the sauce and serve
Melt 1 tablespoon of butter in a saucepan and season with pepper, a little French mustard, and 1 tablespoon of vinegar.
Add the beans to the saucepan and toss until they are very hot and glazed with the butter.
Serve in a deep dish.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- String beans
- Form the main body of the dish and carry the buttery glaze.
- Butter
- Adds richness and a glossy coating that clings to the beans.
- French mustard
- Adds a sharp, pungent note that balances the richness of the butter.
- Vinegar
- Adds acidity that brightens the buttery flavor.
The step that matters
Toss the beans until very hot and glazed. Tossing the drained beans in the warm butter mixture coats them evenly and heats them through. Beans added while wet or cool will dilute the sauce and taste flat.
Swap the beans
How well each one fits the dish's main ingredients (butter, pepper, mustard, vinegar):
- Black-eyed peafits about as well
- Beansthe original
- Sesamefits about as well
- Lentilsfits about as well
Fit is the average pairing score against butter, pepper, mustard, vinegar. Candidates are from the same food group and used in at least 100 recipes.
