To achieve fall-off-the-bone tender mutton Rogan Josh, use slow cooking methods like simmering or pressure cooking, and ensure the mutton is properly browned before adding liquids. Marinating the mutton beforehand also helps tenderize the meat.
Making a rich and tender Mutton Rogan Josh involves several key steps:
Choose the Right Cut: Opt for cuts like shoulder or leg, which have connective tissue that breaks down during slow cooking, resulting in tenderness. Cut the mutton into 1-2 inch pieces.
Marination: Marinate the mutton for at least 2-3 hours, or preferably overnight. A good marinade includes:
Yogurt: Helps tenderize the meat.
Ginger-Garlic Paste: Adds flavor and aids in tenderization.
Spices (Turmeric, Red Chili Powder, Coriander Powder): Infuses flavor.
Browning the Mutton: Sear the marinated mutton in batches in hot oil or ghee until browned on all sides. This step is crucial for developing a rich, deep flavor.
Sautéing Aromatics: In the same pot, sauté finely chopped onions until golden brown. Add ginger-garlic paste and sauté until the raw smell disappears. Then, add the spice powders (Kashmiri red chili powder for color, coriander powder, cumin powder, garam masala) and sauté briefly.
Slow Cooking: Add the browned mutton back to the pot. Pour in enough water or stock to cover the meat. Bring to a simmer, then reduce the heat to low, cover, and cook for 2-3 hours, or until the mutton is extremely tender. Alternatively, use a pressure cooker for about 6-8 whistles on medium heat, followed by natural pressure release.
Finishing Touches: Once the mutton is tender, adjust the seasoning with salt. You can also add a touch of dried ginger powder (sonth) for an authentic flavor. Simmer uncovered for the last 15-20 minutes to allow the sauce to thicken.
Lal Rogan (Optional): For the signature red oil on top, heat a tablespoon of oil in a separate pan. Add a teaspoon of Kashmiri red chili powder and immediately pour it over the Rogan Josh. Be careful not to burn the chili powder.
Avoid adding salt at the beginning of the cooking process, as it can toughen the meat. Add salt towards the end, once the mutton is almost cooked through.
