Goat or mutton, marinated for hours, then browned hard and reduced for the better part of three hours until the sauce clings rather than pools, a Sunday and festival dish rather than everyday food, closely associated with Shyambazar's long-running Golbari restaurant, whose version Kolkata home cooks openly try to replicate.
As tradition built it
Serves 6. About 3 hours, plus 8 hours marinating.
Ingredients
- 1kg mutton or goat, bone-in
- 100g onion, blended to a paste
- 5g garlic, blended
- 100g yoghurt
- 15g salt
- 5g turmeric
- 3g garam masala
For the gravy
- 20g mustard oil, for tempering
- 1 cinnamon stick, 10cm
- 10 green cardamom
- 1 black cardamom
- 10 cloves
- 4 dried red chillies
- 6 bay leaves
- 400g onion, thinly sliced
- 40g ginger paste
- 10g garlic, chopped
- 20g green chilli, chopped
- 3g each coriander, cumin and Kashmiri chilli powder
- 150 to 200g yoghurt
- 10g sugar
- 5g ghee, to finish
Method
- Blend the marinade ingredients, including the turmeric and garam masala, and work into the mutton or goat. Refrigerate 8 hours.
- Temper the mustard oil with the whole spices, the cinnamon stick, green cardamom, black cardamom, cloves, dried red chillies and bay leaves, then fry the sliced onion until deeply golden, roughly 15 minutes.
- Add the ginger paste, garlic and green chilli, cook 5 minutes, then add the ground spice paste of coriander, cumin and Kashmiri chilli powder, loosened with a little water, and cook until dark brown, roughly 30 minutes.
- Add the marinated meat and brown hard on high heat for 15 minutes.
- Stir in the yoghurt, salt and sugar. Over the next 90 minutes, add water in small, roughly 30ml, additions at a time, stirring and covering between each, until the meat is deeply browned and the sauce has reduced to cling rather than pool (Rung 3).
- Finish with the sliced green chilli, cover until the meat is fully tender, then stir through the ghee.
What a modern chef changes
The reduction read by the pan, not the timer
Rung 3
Method
- Use a wide, heavy cast-iron pan or a Big Green Egg's own surface rather than a narrow pot, so evaporation happens faster and more evenly across the whole reduction.
- Let the sauce catch and deglaze it back in, deliberately, at each of the water additions in step 5, rather than avoiding any colour on the pan base.
- Rest the finished dish, covered, off the heat for 15 minutes before serving, the same logic Rannaghor applies to its own mangsho bhaat, reported reworked as a risotto finished with bone marrow butter, a genuine restaurant elevation this chapter names as theirs rather than claiming as a tested house method.
