Instructions

1. 1

   Whisk the yogurt until completely smooth, then keep it at room temperature so it blends without splitting. Mix the Kashmiri chili powder with 60 ml warm water to make a loose paste, which helps the color bloom evenly.

2. 2

   Heat the vegetable oil in a heavy pot over medium heat for 2 minutes until it shimmers. Add ratan jot (if using) and fry for 45–60 seconds, then strain it out with a spoon so only the red-tinted oil remains.

3. 3

   Add bay leaf, cinnamon, cloves, and both cardamoms to the hot oil and stir for 30 seconds until fragrant. Add sliced onions and cook for 10–12 minutes, stirring often, until golden-brown and sweet rather than dark and bitter.

4. 4

   Stir in grated ginger, grated garlic, and the slit green chilies, cooking for 2 minutes to remove raw sharpness. Add cumin powder, coriander powder, turmeric, fennel powder, dry ginger powder, and asafoetida, and cook for 30–45 seconds while stirring so the spices toast but do not scorch.

5. 5

   Add the lamb pieces and 6 g of the salt, then raise heat to medium-high and sear for 8–10 minutes, turning often to coat in the spiced oil. This step builds the base flavor and helps the lamb hold its shape during the long simmer.

6. 6

   Lower the heat to low and add the whisked yogurt in 4 additions, stirring constantly after each addition for 60–90 seconds. Keep the pot gently bubbling, because a hard boil can split the yogurt and make the gravy grainy.

7. 7

   Stir in the prepared Kashmiri chili paste and cook for 3 minutes so the color deepens and the raw chili aroma disappears. Add 440 ml of the warm water and the remaining 6 g salt, then bring to a gentle simmer.

8. 8

   Cover and simmer on very low heat for 75–90 minutes, stirring every 15 minutes and adding up to 60 ml extra warm water if the pot looks dry. The lamb is ready when it is tender and the oil begins to separate lightly at the edges of the gravy.

9. 9

   Uncover and simmer for 8–12 minutes to thicken to a velvety, spoon-coating consistency. Rest the Rogan Josh off the heat for 10 minutes so the flavors settle and the surface oil turns a signature red.
