Method to make the meatballs :
Take a large bowl and add the minced meat into it. Now add the finely chopped onions, garlic, ginger, green chilies and curry leaves. Add the powdered masala (2 teaspoons) into the bowl. Add the required salt and pepper too. Mix them well with your hands so that all the ingredients get incorporated well.
Once the ingredients have blended well, make them into small meatballs. Keep them covered and refrigerated till we are ready to put them into our dumpling curry.
Method to make the curry/sauce :
Take a medium/large saucepan. Heat about five tablespoons of oil. Add the sliced onions, garlic, ginger, green chilies and sauté them till it is soft. Add the masala paste and keep stirring till a nice aroma comes or till the oil separates from the masala. Add the thin coconut milk and reduce the heat. Once the coconut milk comes to a boil, add the meatballs into the sauce, one by one. Add salt and vinegar, to your taste.
Allow the meatballs to get cooked on a medium flame. It is not safe to stir the curry unless the meatballs are cooked. Allow the meatballs to get cooked without putting a lid on the pan, so that the sauce thickens. Once they are cooked, add the thick milk and when it is close to a boil, stir the curry slowly and switch off the stove.
