Why it works: Carrot and parsley 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 ↓
Green Pease Soup
Ingredients
Directions
Prepare the broth
Shell the peas and wash the shells.
Boil the shells in the broth for 30 minutes, then strain them out.
Bring the broth back to a boil and add the peas, salt, carrots, onions, lettuces, and parsley.
Boil for 30 minutes, then serve.
Thicken and finish
For thickened soup, boil the old peas until they can be mashed through a colander.
Stir the pea pulp into the broth and simmer for 1 hour.
Add the bread crumbs and boil for a few minutes.
Boil the young peas separately and stir them into the soup before serving.
Season with salt and sugar, and add butter to the tureen before pouring in the soup.
Optionally, add fried cucumber slices just before serving.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Green peas
- Provide the main body and flavour, and thicken the soup when mashed into pulp.
- Bread crumbs
- Thicken the broth as they cook, giving the soup a fuller body.
- Butter
- Adds richness and a silky mouthfeel to the soup.
- Broth
- Forms the liquid base that carries the flavour of the whole soup.
- Lettuces
- Add a soft, mild vegetable flavour and body as they cook down.
The step that matters
Boil the old peas until they can be mashed through a colander. Cooking the peas until fully tender lets the starch and pulp break down, so the purée passes smoothly through a colander and thickens the soup evenly instead of leaving lumps.
