In a mixing bowl, add all the ingredients and mix to make a dough. There is no need to add any water as the mashed potatoes are the binding agent.
Make 8 to 9 equal portions of the dough and make ball shapes of them about the size of a big lemon.
Place the polythene paper on a plate. Place one of the portion in the center and make a circle of about 3 inches in diameter. Gently pat the dough to flatten it out.
Place a non-stick tava on the gas on high flame. When the tava is hot, reduce the flame to low. Gently slide the prepared thalipeeth on the hot tava.
After about a minute, gently flip the thalipeeth to the other side. Once there are fine brown spots on the surface of the thalipeeth, they are done and transfer to a plate.
In the same manner prepare the remaining thailpeeths. Serve hot with Tamarind Date Chutney and Yogurt.
