Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Rump steak
- Provides meaty flavour and body to the broth as it slowly stews.
- Mutton
- Adds rich meat flavour and tender texture after gentle, long stewing.
- Spanish onion
- Sweetens and deepens the stew's flavour as it cooks down.
- Potatoes
- Absorb the savoury juices and thicken the stew as their starch softens.
The step that matters
Stew gently for 2 hours. A gentle simmer lets collagen in the steak and mutton break down into tender meat and enriches the liquid. Boiling hard toughens muscle fibres and can make the meat dry and stringy.
