Why it works: Parsley and carrot match in chemistry and in kitchens. They rank in the top 1% of all ingredient pairs, and cooks put them together in 8,053 recipes. Both carry 2,4-decadienal, which smells seaweed. The science ↓
Potage a LA Puree De Pois, or Pea Soup
Ingredients
Directions
Prepare the vegetables
Combine peas, lettuces, green onions, parsley, mint, carrot, and salt in a large pot of boiling water. Boil until tender, then drain in a sieve.
Melt butter over low heat in a clean pot.
Add peas and a small ladle of consomme to the butter, cooking until they thicken and are ready to pass through a fine sieve.
Pass the peas through the fine sieve into a soup pot.
Prepare the cucumbers
Fry diced cucumbers in clarified butter until golden brown, then drain.
Simmer the drained cucumbers in a pint of consomme until reduced by half.
Finish and serve
About 30 minutes before serving, heat the soup over low heat, stirring until it boils.
If the soup is too thick, add more consomme to achieve a creamy consistency.
Stir in cucumbers, sugar, and salt to taste 15 minutes before serving.
Skim off any scum that rises.
Serve with toast squares in the tureen.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Peas
- Form the body of the soup, thickening into a smooth purée when passed through a sieve.
- Butter
- Adds richness and fat, carrying flavour through the soup.
- Consomme
- Provides savoury liquid that loosens the purée to a creamy consistency.
- Cucumbers
- Add texture and a light fresh flavour once fried and simmered.
- Cabbage lettuces
- Add green body and mild flavour as they cook down with the peas.
The step that matters
Passing the peas through a fine sieve. Peas must be cooked until fully tender and then pressed through a fine sieve to break down their cell walls, producing a smooth texture. Undercooked or unstrained peas leave a grainy, lumpy soup.
Swap the mint
How well each one fits the dish's main ingredients (peas, cabbage, lettuce, onion, parsley, carrot, butter):
- Celeryfits better
- Tarragonfits better
- Thymefits better
- Mintthe original
Fit is the average pairing score against peas, cabbage, lettuce, onion, parsley, carrot, butter. Candidates are from the same food group and used in at least 100 recipes.
