For my Non-Bengali friends who have no clue
about it let me explain a bit. KOSHA MANGSHO is an exclusive
Bengali dish where mutton is slow cooked into a hot, spicy
gravy and simmered into that thick rich gravy. Every regions of India has a
similar dish but each recipe is different with their own exclusive spices and
cooking techniques.
So, here we go with the authentic "KOSHA
MANGSHO AKA BENGALI MUTTON KOSHA”
Level:
Average difficulty
Prep time: 12 hrs
Cook time: 1.30 hrs
Total time: 13.30 hrs
Serves: 6
Ingredients:
1 kg goat meat cut into chunky pieces
For the marinade:
- 1/2
cup of hung yogurt or Greek yogurt
- 1
1/2 tsp coriander powder
For tempering the oil:
For cooking:
- 3
large onions made into a paste
- 3
medium tomatoes, pureed
- 1
tsp garam masala powder
Instructions:
Mix all the marinating ingredients
in a bowl and add the mutton pieces to it. Mix well and let it marinate in the
refrigerator for at least 12 hours. Do not add salt to the marinade. When the
mutton has marinated for long enough, take a pressure cooker and
heat the remaining mustard oil in it. Temper the oil with the whole spices
(about 30 seconds) and add the onion paste. When the onion turns slightly brown
add the ginger and garlic paste. Sauté over medium heat for 4-5 minutes and
then add the tomato puree. Cook until the tomato has turned a darker red
.Add the cumin and coriander powder and cook for 2 more minutes. Now
add the mutton pieces with the marinade. Mix well before adding the
warm water. When it comes to a boil, cover with the lid and pressure cook until
the meat is soft (takes about 20-35 minutes depending on the cooker).When the
steam has escaped, open the lid and let the meat slow cook for at least 90
minutes, stirring occasionally. Sprinkle the garam masala powder and pour ghee
just before turning off the heat. Serve with steamed rice or roti.

Tips:
1.
Do not ever add salt
into the marinade. Otherwise the mutton will release water and that will dilute
the marinate
