Sticking to the pot is mainly because your pot is too cold. You need to burn the pot around the slightly reddish color. If you put cold oil in it, it won't stick to the pan.

Corn and starch stick together because there is too much water in corn and too much surface water. At this time, when you sprinkle starch, the starch will melt and stick to each other.

When frying corn with starch, there must be more oil in the pot, otherwise it will stick to the pot or stick to each other.
