Why it works: Peas and pepper are a kitchen classic. They rank in the top 15% of all ingredient pairs, and cooks put them together in 5,331 recipes. Both carry 2-isopropyl-3-methoxypyrazine, which smells earthy, pea. The science ↓

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Green peas
- The main ingredient; boiling softens their starches until they become tender.
- Butter
- Adds fat, which gives the peas a richer taste and smoother mouthfeel.
- Sugar
- Adds a touch of sweetness that balances the peas' natural vegetable flavor.
The step that matters
Boil until tender, then stop. Peas cook quickly. Boiling them too long turns them mushy and dulls their bright green color, so check them often and drain once they are just tender.
Swap the peas
How well each one fits the dish's main ingredients (butter, pepper, sugar):
- Almondfits better
- Chestnutfits better
- Walnutfits better
- Peasthe original
Fit is the average pairing score against butter, pepper, sugar. Candidates are from the same food group and used in at least 100 recipes.
