Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Mutton
- Provides the meat and rich flavour that the stew is built around.
- Salted barley flour
- Coats the mutton, helping to thicken the cooking juices and add body.
- Potatoes
- Add starch and bulk, softening during slow cooking to thicken the stew.
- Onions
- Add sweetness and aroma as they soften and release their flavour into the stew.
The step that matters
Seal the bag and cook slowly. A tightly sealed bag traps steam so the meat and vegetables cook in their own moisture. Slow, low heat keeps the mutton tender and prevents the juices from becoming dry or tough.
Swap the onion
How well each one fits the dish's main ingredients (mutton, barley, flour, pepper, potato):
- Leekfits better

- Asparagusfits better
- Onionthe original
Fit is the average pairing score against mutton, barley, flour, pepper, potato. Candidates are from the same food group and used in at least 100 recipes.
