In a pressure cooker put 2 chopped onions and add the mutton pieces.
To it add salt and add one portion of the crushed mixture, 10 curry leaves, 5 green chillies and one table spoon of oil. Mix all these ingredients for a few minutes.
Add water to it and pressure cook the mutton on low flame for approx 4 to 6 whistles. Strain it and keep the stock.
In another pan, heat oil and add the remaining portion of the crushed mixture. Saute it well.
To this add the cooked mutton pieces and mix it well.
Toss in the diced and boiled potatoes. Let it cook over low flame with a lid covering the pan and sir it in intervals.
In the mean time, add the instant coconut mix to the stock in the pressure cooker and mix well.
Note: clumping of this mix is common so constant stirring is warranted.
Then add this mix to the mutton and stir it once well. Do not over cook once the coconut mix - stock has been added. Remove from flame once it starts bubbling.
Garnish with coriander leaves.
Naadan mutton masala is ready. Serve hot with rice, appam, chappati, porotta.
