Take big , round potatoes to make Potato Chips. Potaotes should be big, round, and equal in size. Peel the potatoes and wash them under the running water.
Cut the potatoes into thin slices with the help of chips cutter or any food processor. You can also use sharp knife to cut thin slices. The slices should be thin and equal in size.
Boil 1 ltr. water in a deep pan. The pan should be enough deep so that all the chips can be soaked at one time in it. Add alum into the pan. Alum brings good colour to the potatoes. In case alum (phitkari) is not available, then you can use 1 table spoon vinegar also. Dip all the chips into the pan and leave it for half an hour.
Take them out of the water and wash them with fresh water. Strain the water from the chips and wipe the water from them with a clean cloth.
Heat oil in a pan and put the chips to it. Put as many chips that can be dipped totally in the oil. Do not fry at high heat else the chips will turn brown too soon. Fry the chips at medium or low flame. In might take 5-7 minutes to fry the chips. Take them out of the pan once the chips get crispy. Fry the rest of the chips in the same manner.
Sprinkle salt and black pepper powder on the chips. You can eat this Spicy Crispy Potato Chips right now or store them in an air-tight container and serve it later with tea or coffee in the evening snack.
