Instructions

1. Marinate the mutton

   In a mixing bowl combine the mutton pieces with yogurt, 10 g salt, turmeric, shahi garam masala, ginger paste, crushed garlic‑green‑chili paste, and a pinch of green cardamom. Mix until the meat is evenly coated, cover and refrigerate.

   Time: PT30M

   Temperature: 25°C

2. Prepare the spice paste

   Using a mortar‑pestle or the side of a chef’s knife, crush the garlic cloves together with the green chilies into a smooth paste.

   Time: PT5M

3. Heat mustard oil

   Place the pot over high heat, add 20 ml mustard oil and heat until it lightly smokes and turns a pale yellow.

   Time: PT2M

   Temperature: high (≈200°C)

4. Temper whole spices

   Add dried red chilies, bay leaves, big (black) cardamom, black cardamom, cloves and the cinnamon stick. Fry for about 2 minutes until fragrant.

   Time: PT2M

   Temperature: medium‑high

5. Caramelise the onions

   Add the sliced onions to the pot. Fry, stirring frequently, until they turn a deep, rich brown – about 30 minutes. This slow caramelisation builds the curry’s body.

   Time: PT30M

   Temperature: medium‑high

6. Brown the marinated mutton

   Increase the heat to high and add the marinated mutton. Stir constantly and brown the pieces for about 15 minutes until they develop a deep mahogany colour.

   Time: PT15M

   Temperature: high

7. Add salt and sugar for controlled browning

   Sprinkle 8 g salt and 10 g sugar over the meat. Continue to fry for another 10 minutes, stirring often. The sugar helps achieve a glossy, caramelised surface without burning.

   Time: PT10M

   Temperature: high

8. Slow simmer with incremental water

   Place a 1‑liter jar of hot water nearby. Add roughly 30 ml of hot water to the pot, stir, cover for 1 minute, then uncover and scrape the browned bits from the bottom. Repeat this process over the next 2 hours, adding water in small increments each time, until the meat is dark and the flavors have melded.

   Time: PT2H

   Temperature: medium

9. Adjust gravy and finish cooking

   Add additional water to reach your desired gravy consistency (usually 200‑300 ml). Cover and simmer on low‑medium heat until the meat is fork‑tender and can be pulled apart with two fingers, about 30 minutes.

   Time: PT30M

   Temperature: low‑medium

10. Finish with ghee

    Stir in 100 g ghee until fully melted and incorporated. Let the curry rest for 5 minutes before serving.

    Time: PT5M
