Mutton Rogan Josh is a variation of the classic dish where mutton, or mature lamb, is used instead of regular lamb. The mutton is marinated in yogurt and spices, then cooked in a rich and aromatic gravy made from onions, tomatoes, ginger, garlic, and a blend of spices. The slow cooking process allows the mutton to become tender and flavorful. Mutton Rogan Josh is a hearty and satisfying dish that is best enjoyed with rice, naan bread, or even with a side of raita.
