Instructions

1. 1

   Make the vindaloo marinade by blending the vinegar, garlic, ginger, Kashmiri chili powder, hot chili powder, turmeric, cumin, coriander, black pepper, cinnamon, cloves, and salt into a smooth paste. Coat the lamb thoroughly with the paste, cover, and refrigerate for 12 hours so the vinegar and spices penetrate the meat.

2. 2

   Set a heavy pot over medium heat and add the oil, then warm it for 60 seconds until it shimmers. Add cumin seeds and mustard seeds and cook for 30–45 seconds until they crackle, then add cardamom and bay leaf to perfume the oil.

3. 3

   Add the sliced onions and cook for 12–15 minutes, stirring often, until they turn deep golden brown with some darker edges. This browning is essential because it provides the curry’s backbone and helps tame the sharpness of the vinegar.

4. 4

   Stir in the tomato paste and cook for 2 minutes to caramelize it and remove any raw taste. Scrape the bottom of the pot as you stir so the browned bits dissolve into the onions and build a richer sauce.

5. 5

   Add the marinated lamb along with all the marinade and increase heat to medium-high for 6–8 minutes, stirring to lightly sear the meat. Keep stirring until the paste darkens slightly and clings to the lamb, which concentrates flavor before simmering.

6. 6

   Pour in 500 ml water and bring the pot to a steady simmer, then reduce heat to low and cover. Cook for 70–80 minutes, stirring every 15 minutes, until the lamb is fork-tender and the sauce is thick; add up to 60 ml water if it ever looks dry or begins to stick.

7. 7

   Uncover and simmer for 8–10 minutes to reduce the sauce to a glossy, spoon-coating consistency. Stir in the brown sugar and the finishing vinegar, then cook 1 minute more so the flavors round out without losing the vinegar’s brightness.

8. 8

   Turn off the heat and rest the vindaloo for 10 minutes so the oil and spices settle into the sauce. Garnish with cilantro and serve hot, making sure each portion gets both tender lamb and plenty of tangy gravy.
