Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- String beans
- Provide the main body of the dish, cooked until tender before sautéing.
- Butter
- Adds fat and richness, carrying flavor across the beans as they heat.
- Chopped onion
- Adds mild aromatic sweetness and savory depth when warmed in the pan.
- Chopped green herbs
- Contribute fresh aroma and bright flavor to the buttery beans.
The step that matters
Toss the beans only until hot. The beans are already cooked, so extended heating in the pan can make them soft and dull in color. Brief tossing with butter keeps them tender-crisp and bright while the flavors coat the surface.
Swap the beans
How well each one fits the dish's main ingredients (butter, onion, pepper):
- Black-eyed peafits about as well
- Sesamefits about as well
- Beansthe original
- Soybeanfits less well
Fit is the average pairing score against butter, onion, pepper. Candidates are from the same food group and used in at least 100 recipes.
