Cut the sweet potato into half and pressure cook for 3 whistles or until sweet potato is cooked well with some salt.Peel the skin and grate or mash the sweet potato.
In a bowl add wheat flour ,boiled & grated sweet potato, coriander leaves ,ajwain ,ginger, turmeric powder, red chilli powder, garam masala ,amchur powder ,oil and salt. Mix well.
Add very little water and make a smooth (but not sticky) dough. Smear little oil on the dough and let it rest for at-least 10-15 mins.
Make balls from the dough. I was able to get 6 balls.
Roll the parathas semi thick/ thin by dusting some dry flour
Heat up a tawa/skillet on medium heat and place the paratha and let it cook.Once you see bubbles ,flip on to other side drizzle some ghee or oil on top.Flip again and drizzle oil or ghee on the other side as well till they have nice golden spots on both sides.
Serve Sweet Potato Paratha with curd, pickle, raita ,ketchup or any gravy of your choice.
