1. Mix all the ingredients for the dough in a mixing bowl and knead well.
2. Add water if the milk is not enough; Keep aside for about 15 mins
3. Meanwhile, mix together all the ingredients for the filling;
4. Adjust the masalas and salt according to your taste. Make sure the potatoes are mashed well.
5. Pull out small lemon sized balls from the dough and roll them into small/mini rotis with a rolling pin.
6. Make a lemon sized ball out of the filling and place it in the center of the roti.
7. Quantity of the filling should be the same as the size of the dough that you took in the previous step or a little more.
8. Cover the filling with the roti from all sides and seal well.
9. Roll into circular parathas with the rolling pin.
10. Sprinkle dry wheat flour on the paratha if required.
11. Make sure not to apply too much pressure.... the filling would ooze out otherwise.
12. Heat a tava and cook the parathas on both the sides until done.
13. You don't need to add oil/ghee while cooking.
14. The curds and the milk that we added while kneading the dough makes it soft enough!
15. Remove from tava and serve hot with curds/pickle or any other side dish of your choice.
