Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs

What each ingredient does

Mutton
Provides the rich meat flavour and tender texture after long, gentle simmering.
Potatoes
Thicken the stew as their starch softens and absorbs the cooking liquid.
Onions
Add sweetness and aroma as they soften and mellow during slow cooking.

The step that matters

Simmer gently without boiling hard. A hard boil toughens the meat proteins and breaks up the potatoes, while gentle simmering lets collagen slowly soften into tender meat and keeps the stew clear.
