Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Marrowfat peas
- Their starch softens during soaking and boiling, giving the dish its thick, mealy body.
- Sugar
- Adds a mild sweetness that balances the savoury salt and the earthy flavour of the peas.
- Butter
- Adds fat and richness, softening the texture and rounding out the flavour when stirred in.
The step that matters
Gently boil for 40 minutes. A vigorous, rolling boil can break the peas apart and make them ragged. A gentle simmer lets them soften evenly while they hold their shape.
Swap the mint
The recipe marks mint as optional. How well each one fits the dish's main ingredients (peas, sugar, butter):
- Cinnamonfits better
- Mintthe original
- Gingerfits about as well
- Tarragonfits less well
Fit is the average pairing score against peas, sugar, butter. Candidates are from the same food group and used in at least 100 recipes.
