Step 1: Prepare the Kadai Masala
On medium heat, dry roast fennel seeds, coriander seeds, cumin seeds, red chilies, cloves, cinnamon, black cardamoms, and green cardamoms for about 2 to 3 minutes until aromatic but not burnt.
Allow the spices to cool completely.
Grind the roasted spices into a fine powder.
Set the kadai masala aside.
Step 2: Cook the Mutton
Heat ghee or oil in a large wok or kadai over medium flame.
Add chopped onions and sauté until they turn transparent.
Stir in the ginger garlic paste and cook for 1 to 2 minutes without burning.
Add the lamb or mutton pieces and sauté for 5 to 6 minutes until the color changes.
Mix in turmeric, cumin seeds, and part of the prepared kadai masala.
Cover the pan and cook on low heat.
Add hot water slowly if needed, stirring occasionally.
Simmer gently for about 2 hours or until the lamb becomes tender.
Step 3: Prepare the Gravy
Once the lamb is tender, add the pureed tomatoes and stir well.
Cover and cook for another 35 to 40 minutes until the oil separates and the sauce thickens.
Take a few tablespoons of kadai gravy (to temper) and mix it with yogurt in a small bowl.
Add the tempered yogurt back into the pan and stir well.
Sprinkle crushed kasuri methi, freshly cracked black pepper, and a few chili flakes.
Adjust salt and consistency with a splash of hot water if needed.
Step 4: Final Bhunai and Garnishing
Perform the final bhunai by cooking the curry on high flame until you see fats rising to the top.
Garnish with ginger juliennes, sliced green chilies, and coriander leaves.
Serve hot in a straight pan or traditional kadai for the best flavor.
Step 5: Storing and Reheating
Allow the Mutton Kadai to cool completely at room temperature.
Transfer it into an airtight container.
Store in the refrigerator for 3 to 4 days or freeze for up to 2 months.
When reheating, warm slowly on the stove over low heat, adding a splash of water if the gravy thickens too much
