Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Young french beans
- Provide the main body of the dish and become tender when boiled.
- Butter
- Adds richness and moisture, carrying the herb flavours over the beans.
The step that matters
Boil the beans until tender. Beans cooked too briefly stay tough and fibrous, while overcooking makes them soft and dull in colour. Testing a piece for tenderness helps hit the point where they are cooked through but still hold their shape.
Swap the shallot
The recipe marks shallot as optional. How well each one fits the dish's main ingredients (beans, butter, parsley, garden cress, pepper, nutmeg):
- Shallotthe original
- Lettucefits about as well
- Chivefits less well
- Mustardfits less well
Fit is the average pairing score against beans, butter, parsley, garden cress, pepper, nutmeg. Candidates are from the same food group and used in at least 100 recipes.
