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, which becomes tender as the slices stew slowly in liquid.
- Butter and flour
- Flour thickens the cooking liquid into a richer sauce, and butter adds fat and smooth body.
- Broth
- Supplies the liquid that cooks the meat gently and forms the base of the sauce.
- Onions
- Soften during stewing and add sweetness and savoury depth to the sauce.
- Mushroom ketchup
- Adds concentrated savoury, umami flavour to the finished stew.
The step that matters
Stewing without overcooking. Mutton is tough connective tissue that needs slow, moist heat to turn tender, but prolonged boiling toughens and dries muscle fibres. Keeping a gentle simmer and checking early helps the meat stay tender and juicy.
