Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- French beans
- Form the main body of the dish, providing the vegetable bulk and tender texture when cooked.
- Butter
- Adds fat and richness, coating the beans for a smoother mouthfeel and flavour.
The step that matters
Boil until tender. Boiling in well-salted water seasons the beans from within and cooks them evenly. Stopping at the right moment keeps them tender yet still bright green rather than dull and overcooked.
Swap the beans
How well each one fits the dish's main ingredients (butter, pepper):
- Walnutfits about as well
