The trick is to remove all the starch. Rinse it well till the color of water changes to white.( u should remove the starch in potatoes).Ie Discard the water and again wash the potato slices.Repeat this for 2-3 times.
Divya ji...pls soak the chips in ice cold water for 10 minutes, drain them and dry in sunlight. Make a salt water solution. While frying the chips carefully add this salt water solution to the oil so that all chips get evenly salted and crispy.
Hi! Pls chose the potatoes wth thin skin.. these contain less starch. Blanch in hot water.. Let them dry and freeze. U can kerp them in zip lock pouches and fry straight from the freezer
