Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Peas
- Form the main body of the dish, cooking down to a tender texture.
- Butter
- Adds richness and fat, carrying flavour and giving the peas a silky coating.
- Sugar
- Adds a touch of sweetness that balances the savoury onion and salt.
- Chopped onion
- Adds savoury aroma and depth as it softens during stewing.
The step that matters
Stew gently with the lid closed. Gentle heat under a tight lid keeps the peas moist and tender. Boiling hard or lifting the lid can toughen the skins and dry the peas out before they soften.
Swap the onion
How well each one fits the dish's main ingredients (peas, butter, sugar):
