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 ↓

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Mutton
- Provides the main meat flavour and richness as it simmers into the broth.
- Dried peas
- Boiled to a pulp and strained, they thicken the soup and give it body.
- Butter rolled in flour
- A flour-coated fat that thickens the broth and adds richness as it stews.
- Turnips
- Soften during slow boiling and add mild sweetness and body to the broth.
- Carrots
- Soften during slow boiling and add sweetness and colour to the broth.
The step that matters
Incorporating the butter rolled in flour. Flour-coated butter must be stirred in gently and kept simmering so the flour hydrates and cooks out fully; otherwise it stays floury or forms lumps and the soup tastes raw.
Swap the peas
How well each one fits the dish's main ingredients (mutton, turnip, carrot, onion, cabbage, lettuce, parsley):
- Lentilsfits better
- Beansfits better
- Chickpeafits better
- Peasthe original
Fit is the average pairing score against mutton, turnip, carrot, onion, cabbage, lettuce, parsley. Candidates are from the same food group and used in at least 100 recipes.
