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 Peas Soup
Ingredients
Directions
Prepare
Shell and wash the peas.
Boil the pea shells in the broth from veal, lamb, mutton, or fowl for 30 minutes.
Strain the shells and return the broth to a boil.
Make the soup
Add the peas, salt, carrots, onions, lettuce, and parsley to the broth.
Boil for 30 minutes, then serve.
For thick soup, boil a peck of peas, reserving 1 pint of the youngest peas.
Pulp the older peas through a colander and stir into the broth.
Cover and simmer for 1 hour.
Add bread crumbs and boil for a few minutes.
Stir in the reserved young peas and serve.
Season with salt and sugar, adding butter to the tureen before serving.
Fried cucumber garnish
For fried cucumber, slice thin, remove seeds, drain, flour, and fry in butter 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, sweetness and flavor of the soup when pulped into the broth.
- Bread crumbs
- Thicken the broth as they soak up liquid and soften during boiling.
- Butter
- Adds richness and a silky mouthfeel to the finished soup.
- Broth
- Forms the liquid base that carries the flavor of the vegetables and peas.
The step that matters
Pulping the older peas through a colander. Pushing the cooked peas through a sieve breaks down their starch and fibre, which is what gives the soup its body; unpulped peas leave it thin and grainy.
Swap the peas
How well each one fits the dish's main ingredients (carrot, onion, lettuce, parsley, veal, bread, butter):

- Peasthe original
Fit is the average pairing score against carrot, onion, lettuce, parsley, veal, bread, butter. Candidates are from the same food group and used in at least 100 recipes.
