Why it works: Peas and parsley are a kitchen classic. They rank in the top 13% of all ingredient pairs, and cooks put them together in 1,885 recipes. Both carry trans-2-hexenal, which smells green, leafy. The science ↓

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Pea pods
- Simmered in the stock to give it a fresh, green pea flavour.
- Peas
- Form the body and main flavour of the soup once cooked and added back in.
- Drippings
- Fat that carries flavour into the stewpan at the start of cooking.
- Loaf sugar
- Adds a small amount of sweetness that balances the vegetable flavour.
The step that matters
Simmering the peas until tender. Cooking on low heat under a cover keeps the peas gently softened and green. Boiling hard or cooking too long dulls the colour and flavour, and under-cooked peas leave the soup starchy and grainy.
Swap the parsley
How well each one fits the dish's main ingredients (peas, sugar):
- Mintfits better
- Cinnamonfits better
- Gingerfits better
- Parsleythe original
Fit is the average pairing score against peas, sugar. Candidates are from the same food group and used in at least 100 recipes.
