Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Green peas
- Form the main body of the dish and carry the buttery mint flavour.
- Butter
- Adds richness and a smooth, fatty mouthfeel that carries the mint flavour.
- Mint lettuce
- Infuses the cooking water with a fresh, aromatic mint flavour.
- Onion
- Adds a mild aromatic background flavour to the cooking water.
- Sugar
- Adds gentle sweetness that balances the savoury salt and herb notes.
The step that matters
Mixing the mint into cold butter. Butter kept cold stays firm enough to blend with the minced mint without melting or separating. Blanching the mint first helps it keep a bright green colour in the finished butter.
Swap the onion
How well each one fits the dish's main ingredients (peas, butter, mint, lettuce, sugar):
- Cucumberfits better
- Beetrootfits better
- Leekfits better
- Onionthe original
Fit is the average pairing score against peas, butter, mint, lettuce, sugar. Candidates are from the same food group and used in at least 100 recipes.
