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, whose connective tissue softens into tender bites during long simmering.
- Small potatoes
- Break down slightly as they cook, adding body and starch that lightly thickens the broth.
- Turnips
- Hold their shape while adding a mildly sweet, earthy flavour to the broth.
- Onions
- Soften and turn sweet as they simmer, adding depth to the broth.
The step that matters
Skimming the foam after the boil. Foam carries impurities from the meat that cloud the broth and taste bitter. Removing it early keeps the stew clear and clean-flavoured.
Swap the turnip
How well each one fits the dish's main ingredients (mutton, meat, pepper, potato, onion):
- Carrotfits better
- Capsicumfits better
- Leekfits about as well
- Turnipthe original
Fit is the average pairing score against mutton, meat, pepper, potato, onion. Candidates are from the same food group and used in at least 100 recipes.
