- Preparation: Boil the potatoes in a pressure cooker or steamer till completely cooked and of mashable consistency. Peel and mash the potatoes coarsely when they are still hot or warm. You can also crumble the potatoes. Keep the roughly mashed potatoes aside. Making Potato Podimas: Heat oil in a pan. Crackle the mustard seeds first. Then add the cumin seeds and let them splutter. Add the green chilies, ginger, curry leaves and asafoetida. Fry for 8-9 seconds. Add the mashed potatoes. Stir well. Add salt and saute for 3-4 minutes on a low flame stirring at times. Add the coriander leaves and saute for 1-2 minutes more on a low flame. Instead of sauteing with coriander leaves, you can also garnish with coriander leaves.
