Why it works: Peas and butter are a kitchen classic. They rank in the top 16% of all ingredient pairs, and cooks put them together in 4,887 recipes. Both carry trans-2-nonenal, which smells cardboard, fatty. The science ↓

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Fresh green peas
- The main ingredient, whose freshness and youth set the flavour and texture of the preserved peas.
- Butter
- Adds richness and a smooth coating to the peas when tossed at serving.
- Sugar
- Adds a touch of sweetness that balances the savoury peas.
The step that matters
Spread the peas on a cloth to dry. Any surface moisture left on the peas dilutes the seal and encourages spoilage once they are covered with fat in the bottles, so they must be fully dry before filling.
Swap the peas
How well each one fits the dish's main ingredients (butter, sugar):
- Almondfits better
- Pecansfits better
- Filbertfits better
- Peasthe original
Fit is the average pairing score against butter, sugar. Candidates are from the same food group and used in at least 100 recipes.
“What each ingredient does” and “The step that matters” were written by Claude from this recipe’s own method and reviewed in samples by CompKitchen.
