Cut the potatoes into small cubes so that they cook faster (or use boiled potatoes)
4 Potatoes
Heat oil in a pan. Add the mustard seeds and cumin seeds. When they start to splutter, add the curry leaves and saute for a few seconds.
1 teaspoon Mustard Seeds, ½ teaspoon Cumin seeds, 1 strand Curry leaves, 2 tablespoon Vegetable oil
Add the onion, ginger, garlic, green chillis, turmeric powder, hing, and salt and saute till the onion becomes light in color.
½ Onion, 1 inch Ginger, 3 to 5 Garlic cloves, 2 to 3 Green chillies, ½ teaspoon Turmeric powder, ¼ teaspoon Asafoetida/Hing, Salt to taste
Add the potatoes and 2 cups of water, and adjust the salt. Mix well, cover it with the lid, and set it on medium to medium-high flame till the potatoes are cooked.
Take a few potatoes and mash them lightly just to adjust the consistency (do not mash all of them, as this style of bhaji is served with cubes of potatoes)
Add coriander leaves and mix; switch off the flame.
2 tablespoon Coriander leaves
Serve hot with poori, chapati, or dosa, and enjoy.
