Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Young french beans
- Form the body of the dish and provide its main texture once cooked until tender.
- Butter
- Adds fat, richness and a smooth mouthfeel that coats the cooked beans.
- Pepper
- Adds a sharp, aromatic bite that contrasts with the mild beans and butter.
The step that matters
Boil the beans until tender. Cooking time decides the texture. Undercooked beans stay tough and fibrous, while overcooked beans turn soft and mushy and lose their fresh colour and bite.
Swap the beans
How well each one fits the dish's main ingredients (butter, pepper):
- Walnutfits about as well
- Black-eyed peafits about as well
