Ingredients
Directions
Prepare
Cut and boil the French beans until tender.
Drain the beans well and place them in a stewpan over medium heat to dry.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- French beans
- The main vegetable; boiling softens them until tender.
- Butter
- Adds fat and richness, and coats the beans with a glossy finish.
- Lemon juice
- Adds acidity that brightens the flavour of the butter.
The step that matters
Drain and dry the beans well. Water left on the beans dilutes the butter and stops it clinging to them. Drying over heat lets the surface moisture evaporate so the butter coats the beans evenly.
Swap the beans
How well each one fits the dish's main ingredients (butter, lemon, pepper):
- Chickpeafits better
- Walnutfits about as well
- Pistachiofits about as well
- Beansthe original
Fit is the average pairing score against butter, lemon, pepper. Candidates are from the same food group and used in at least 100 recipes.
“What each ingredient does” and “The step that matters” were written by Claude from this recipe’s own method and reviewed in samples by CompKitchen.
