Ingredients
Directions
In a stewpan, melt the butter and fry the sliced onions until soft.
Add the gravy and let it stew for about 10 minutes.
Stir in the mutton, walnut ketchup, browning sauce, and lemon pickle, then boil for 3 to 4 minutes, shaking the pan occasionally.
Season with salt and cayenne pepper, then serve hot without thickening the sauce.
Garnish with red cabbage.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Mutton
- Provides the main body of the dish, warmed through in the sauce.
- Onions
- Soften in butter, adding sweetness and a savory base to the sauce.
- Butter
- Carries the frying of the onions and adds richness to the dish.
- Good gravy
- Forms the liquid that the mutton simmers in, giving moisture and savoriness.
- Walnut ketchup
- Adds a dark, tangy, savory depth of flavor to the sauce.
The step that matters
Boiling the mutton in the sauce. Boiling for only 3 to 4 minutes with occasional shaking warms the mutton through without toughening its meat or breaking down the sauce. Boiling too long can make the meat dry and tough.
