• Take 400 gms of potatoes and wash them first. After washing the potatoes peel them using a peeler.
• When you have peeled all the potatoes  wash them again with fresh water. This way all the dirt present in the potatoes will be washed off.
• After washing them, cut the potatoes into rounds of quarter inch. The size of the potatoes should be around ¼ inch round. While you are giving the potato its shape make sure that the potatoes are thick enough for easy cooking.
• You can either deep fry or shallow fry the potatoes depending on your preference.
• In case you are shallow frying the potatoes like we did, then heat a pan and add 2-3 tablespoon of oil in it.
• When the oil starts to heat, place all the round shaped potatoes in one layer.
• When you have kept all the potatoes in the pan, cover the lid of the pan and allow the potatoes to cook for 3 mins.
• After 3 minutes, take off the lid of the pan and flip the sides of the potatoes to allow them to cook from the other side as well. When both the sides of the potatoes is cooked and both the sides are golden brown in color, then go ahead and turn off the heat.
• After that take off the potatoes from the pan in a plate and keep them aside.
