Prep the Potatoes: First, wash, peel, and cut your potatoes into medium-thick slices or wedges. Wash them again to remove excess starch and pat them dry.
Heat the Pan: Place a tawa (griddle) or a flat frying pan on the stove. Add a little oil and let it get nice and hot.
Cook the Potatoes: Carefully place the potato slices on the hot tawa. Cook them on medium heat for about 5-7 minutes.
Flip and Sauté: Keep stirring or flipping them every few minutes so they cook evenly on all sides. These potatoes cook very quickly.
Add the Spices: Once the potatoes are cooked and tender, turn the heat to an absolute low. This is very important to ensure your spices don't burn.
Mix the Masalas: Add all the dry spice powders: salt, red chilli powder, turmeric, garam masala, and the star ingredient, chaat masala.
Toss and Sauté: Gently toss everything together, making sure each potato piece is well-coated with the masalas. Sauté for another 1-2 minutes on low heat.
Garnish and Serve: Finally, add a generous amount of freshly chopped coriander leaves, give it one last mix, and turn off the heat. Your Spicy Tawa Aloo Fry is ready to serve!.
