Why it works: Peas and mint are a kitchen classic. They rank in the top 2% of all ingredient pairs, and cooks put them together in 1,137 recipes. Both carry 1-octen-3-ol, which smells mushroom, earthy. The science ↓

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Peas
- Form the dish's main body and provide its sweet, fresh flavour when cooked gently.
- Butter
- Adds fat for richness and a smooth, rounded mouthfeel to the juices.
- Flour
- Thickens the cooking liquid so it clings to the peas instead of running off.
- Chopped lettuce
- Releases moisture and softens during cooking, adding body to the peas.
- Sugar
- Adds sweetness that balances the savoury salt and the mint.
The step that matters
Sealing the bag for the first bake. A tightly sealed bag traps steam so the peas cook in their own moisture. If it leaks, the peas can dry out before they are tender.
Swap the mint
How well each one fits the dish's main ingredients (peas, sugar, butter, flour, lettuce):
- Capersfits better
- Cinnamonfits better
- Tarragonfits better
- Mintthe original
Fit is the average pairing score against peas, sugar, butter, flour, lettuce. Candidates are from the same food group and used in at least 100 recipes.
