Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Peas
- Provide the main body and sweet, tender texture of the dish.
- Butter
- Adds fat and richness, carrying flavour through the slow cooking.
- Onions
- Add savoury depth and aroma as they soften in the pan.
- Lettuce heart
- Softens into the peas, adding moisture and a mild, tender body.
- Sugar
- Adds sweetness that balances the savoury onion and herbs.
The step that matters
Gradually adding water as it evaporates. Cooking peas slowly on low heat with the pan covered keeps moisture in. If the pan runs dry, the peas and onions can scorch and stick, so water should be added as needed.
Swap the peas
How well each one fits the dish's main ingredients (butter, onion, parsley, thyme, lettuce, sugar):
- Chickpeafits better
- Chestnutfits better
- Lentilsfits better
- Peasthe original
Fit is the average pairing score against butter, onion, parsley, thyme, lettuce, sugar. Candidates are from the same food group and used in at least 100 recipes.
