Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Fillet of mutton
- Forms the main body of the dish, becoming tender through slow stewing.
- Butter
- Browns the surface of the meat, adding colour and a rich roasted flavour.
- Gravy
- Provides liquid for the slow stew, keeping the meat moist as it cooks.
- Onions
- Soften during stewing and add sweetness and savoury depth to the gravy.
The step that matters
Stew slowly for 3½ hours. Low, gentle heat over a long time breaks down the connective tissue in mutton, making it tender. Rushing with high heat toughens the meat and can dry the liquid too quickly.
