Why it works: Lettuce and parsley match in chemistry and in kitchens. They rank in the top 5% of all ingredient pairs, and cooks put them together in 1,483 recipes. Both carry trans-2-hexenal, which smells green, leafy. The science ↓
Green Peas
Ingredients
Directions
Prepare the peas
Shell and wash the peas.
Put the peas in cold water to cook.
When nearly done, add coarse sea salt.
When tender, remove the peas with a little cooking liquid.
Make the stew
In a stew-pan, combine the peas, lettuce, onion, parsley, and ham.
Cover and cook over gentle heat, shaking occasionally.
Add water if necessary to prevent burning.
Once the peas are tender, remove the ham and onion.
Mix the flour with butter and cream.
Stir the flour mixture into the peas.
Simmer gently for 3–4 minutes.
Serve hot.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Green peas
- Form the body of the stew and give it its main texture and sweet flavour.
- Flour
- Thickens the cooking liquid so the stew becomes smooth and lightly body-rich.
- Butter
- Adds fat for a richer mouthfeel and smoother finish.
- Cream
- Adds richness and moisture, softening the stew's finish.
- Ham
- Contributes savoury, salty flavour as it cooks into the stew.
The step that matters
Stirring the flour mixture into the peas. Flour clumps if added raw or unevenly; mixing it first with butter and cream and stirring it in gradually lets starch disperse and thicken smoothly rather than forming lumps.
Swap the peas
How well each one fits the dish's main ingredients (lettuce, onion, parsley, ham, flour, butter, cream):
- Lentilsfits better
- Chestnutfits better
- Pistachiofits better
- Peasthe original
Fit is the average pairing score against lettuce, onion, parsley, ham, flour, butter, cream. Candidates are from the same food group and used in at least 100 recipes.
