Firstly, peel the skin off the potato. Choose special wafer potatoes or red potatoes for perfect results. Then cut off both the upper and lower parts of the potato, which helps to get uniform potato fries pieces. Now slice the potato into 1 cm thick pieces or to the size required.

Wash the potato slices with water, which helps to get rid of excess starch from the potato and makes the fries crispy. Soak the potato slices in ice-cold water for 20-30 minutes. Remove the cold water and quickly dry the French fries either in a washing machine or by spreading them on cotton until no water remains on the fries' surface.

Heat the oil and add the fries to it. Keep the flame on medium and stir continuously until it is cooked 80-90%. Do not fry on high flame. Take out the fries from the hot oil and spread them on a wire rack. Freeze the fries in a tray or ziplock bag for a minimum of 1-2 hours. This helps the fries turn firm.

In the second fry, fry the potatoes on high flame until they turn brown and crispy. Drain the fries onto wire racks once they are golden brown. Sprinkle salt or spices of your choice on French fries. Serve hot with tomato ketchup.

For Masala French fries, take crispy French fries in a bowl and add salt, black pepper powder, red chilli flakes, chaat masala, and some dried parsley leaves. Mix well. Masala French fries are ready to serve with tomato ketchup.
