In Kolkata, Kosha mangsho(especially mutton kosha) is the most popular dish in bengali biye barir menuDurga pujo (Nabami special lunch meal)Kali puja & Viswakarma puja’r dinner feast occasions.

Let’s see how to make kosha mangsho(mutton kosha) recipe step by step with pictures.

How I made mutton kosha (kasha mangsho) in my kitchen?

◙ First marinade the mutton with salt, lemon juice, little mustard oil.

◙ Then fry aloo(potatoes) and fry half of the onion with cinnamon & little sugar.

◙ Blend fried onion with tomato, green chilies, dry red chilies, ginger-garlic paste, yogurt(curd), and cumin-coriander powder for making the masala.

◙ Also, blend the rest half onion and fry with bay leaves until the raw smell of onion goes off.

◙ Add the masala paste with turmeric and kashmiri red chilli powder and slight more well-beaten yogurt.

◙ Roast (bhuna) it well until the oil separates from the masala.

◙ Add the mutton (marinade earlier), mix well with masala, add potatoes, and cook it by covering the pan, Stir frequently.

◙ After 30 mins cooking in this way add salt and cook it for 5 more mins.

◙ At this stage, add garam masala powder, mix well, and cook more 5 mins.

◙ Then add lukewarm water. Once the gravy starts to boil, put it in the pressure cooker.

◙ Cook over slow heat until the pressure cooker whistles 1 time or until the mutton is tender.

◙ Once the pressure cooker cools down, after opening the lid check the gravy, if seems to have more gravy, give it a boil to reduce the gravy.

◙ Once getting thick consistency, turn off the heat, and garnish mutton kosha (kosha mangsho) with chopped coriander leaves or ghee.

Kosha Mangsho(Mutton kosha or Mangsho kasha)

Important Ingredients for kosha mangsho(mutton kosha)!

◙ Mustard Oil – One more must ingredient for making this bengali mutton curry is mustard oil. Any bong-style curry is incomplete without it as the pungent taste will be missing.

◙ Ginger and garlic paste – Onion, ginger, garlic, and green chilli paste are commonly used ingredients for making gravy like other Indian mutton curry recipes. Try to use fresh ginger-garlic paste.

That packet of ginger-garlic paste contains vinegar, oil, and a few preservatives that make a different flavor to the gravy.  That flavor easily changes the authentic taste and flavor of mangsho and its gravy.

◙ Potatoes – Generally kosha mangsho is cooked without potatoes. However, here, I have used 4 medium to large potatoes and cut them into halves. If using small to medium potatoes use as a whole (gota alu). If using large potatoes, cut them into four equal pieces

◙ Garam masala powder –  Here I used a special garam masala containing cinnamon, cardamom, and cloves along with black peppercorn and bay leave to deliver an awesome flavor and taste. Though you can use a simple store-bought packet garam masala powder too. 

Ingredients of Bengali Mutton kosha recipe

Which part of mutton is best to make mutton kosha recipe?

Mutton raan (lamb/goat legs mainly thighs), shanks (upper part of legs), shoulder, and neck are the best for cooking any Indian-style mutton curry as well as this mutton kosha recipe. Just because raan, shanks, shoulder, and neck pieces quickly get tender.

Especially in Bengali cuisine, rewazy khasir mangsho (mutton with thick layer of fat) and kochi pathar mangsho (young goat without fat) are used for making kosha to jhol recipes. Though kochi pathar mangsho is easy to melt in the mouth, and good for people who have health issues (or conscious about consuming fat). 

Store-bought Powder masala or bata moshla, Which is best, for making kosha mangsho(mutton kosha)?

Don’t have enough time to make bata moshla and I do not have grindstone or shil nora (in Bengali). However, bata moshlar is the secret of our authentic Bengali cuisine. To get that authentic taste in your mutton kosha recipe cook it with bata masala, by soaking jeera seeds, coriander seeds, and dry red chili in lukewarm water for 30 mins. Then grind it with other masalas in a grindstone or in a mixer grinder until getting a smooth paste. Add little water if needed during grinding.

Notes

  • If you prefer a thicker gravy, you can add a few tablespoons of mashed potatoes to the pan before adding the water. You can also adjust the spiciness of the dish by increasing or decreasing the amount of red chili powder and green chilies used.
  • If salt is added during the roasting mutton. Mangsho would release water and would not get the desired taste.
  • Even if adding water before perfect roasting(means before releasing oil), makes the taste bland.
  • Using sugar and cinnamon in frying onion will bring that dark brown color to the gravy without using the iron pan or wok.
  • Marinate the mutton overnight (about 8-12 hours. That will help to tenderize the meat and mutton can be cooked in a pan. Otherwise, meat (mangsho) would not be cooked properly.
