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 or lamb
- Gives the soup its meaty flavour and body as it simmers slowly.
- Potatoes
- Grated potatoes thicken the broth and add body to the soup.
- Carrots
- Add natural sweetness and colour to the simmering broth.
- Turnips
- Contribute a mildly sharp, earthy flavour and firm texture to the soup.
- Tomatoes
- Add acidity and fresh flavour, and are added late to keep their shape.
The step that matters
Skim the soup well after it comes to a boil. Bringing the soup to a boil slowly and skimming off the foam that rises removes impurities and fat, keeping the broth clear and clean-tasting.
