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 ↓
Mutton Soup
Ingredients
Directions
Prepare the broth
Soak the neck of mutton thoroughly.
Place the mutton in a pot half full of water and bring to a boil.
Skim the broth well when it comes to a boil.

Shortly before serving, stir in the chopped parsley.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Neck of mutton
- Provides the main meat and rich flavour as it simmers into the broth.
- Barley
- Thickens the broth slightly and adds a soft, chewy texture as it cooks.
- Turnips
- Add mild sweetness and body to the broth as they become tender.
- Onions
- Add savoury depth and sweetness to the broth as they soften.
- Carrots
- Add natural sweetness and colour, becoming tender in the simmering broth.
The step that matters
Skim the broth well when it comes to a boil. Foam and fat rise to the surface as the broth heats. Removing them early keeps the soup clear and prevents a greasy, cloudy result.
Swap the onion
How well each one fits the dish's main ingredients (mutton, turnip, carrot, barley, parsley):
- Leekfits better
- Parsnipfits better
- Shallotfits better
- Onionthe original
Fit is the average pairing score against mutton, turnip, carrot, barley, parsley. Candidates are from the same food group and used in at least 100 recipes.
