Why it works: Turnip and carrot match in chemistry and in kitchens. They rank in the top 1% of all ingredient pairs, and cooks put them together in 8,002 recipes. Both carry coumarin, which smells sweet, hay. The science ↓
Harrico Mutton Soup
Ingredients
Directions
Make the broth
Divide the neck of mutton into two parts.
Place the scrag end in a stewpan with turnips, carrots, onion, and water.
Stew gently over low heat for 2 hours until the mutton is tender.
Thicken and finish
Bruise 2 turnips and 1 carrot through a colander to thicken the soup.
Cut the other part of the mutton into chops and brown them in a pan.
Add the chops to the soup and simmer gently until tender.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Mutton neck
- Gives the soup its meaty flavour and rich body as it stews.
- Turnips
- Bruised turnips break down into the soup, thickening it and adding body.
- Carrots
- Bruised carrots dissolve into the broth, adding sweetness and thickness.
- Flour
- Starch thickens the soup as the liquid simmers.
- Mushroom ketchup
- Adds deep savoury, umami flavour to the broth.
The step that matters
Brown the mutton chops before adding them to the soup. Browning creates Maillard flavour compounds on the surface of the meat, which add depth that simmering alone does not produce. Pale chops give a flatter-tasting soup.
Swap the onion
How well each one fits the dish's main ingredients (mutton, turnip, carrot, flour, mushroom, ketchup):
- Leekfits better
- Shallotfits better
- Arrowrootfits better
- Onionthe original
Fit is the average pairing score against mutton, turnip, carrot, flour, mushroom, ketchup. Candidates are from the same food group and used in at least 100 recipes.
