Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Broad beans
- Form the main body of the dish, giving it its tender, vegetable texture.
- Butter
- Adds fat and richness, carrying flavour and giving the beans a smooth coating.
- White sauce
- Adds moisture and a creamy body that binds the beans together.
- Parsley
- Contributes fresh, green aroma and a light herbal flavour.
- Tarragon
- Adds a distinctive aniseed-like aroma that lifts the buttery flavour.
The step that matters
Simmer gently until the beans are tender. High heat can toughen the beans and break the butter and white sauce, which can separate or turn greasy. Gentle simmering lets the beans soften evenly while the sauce stays smooth and cohesive.
Swap the beans
