One should be mindful of not adding the corn starch directly to a lot of liquid as it will become lumpy. It should be added to a small bowl with warm or temperate water to make a slurry-like consistency and then added to the main dish to thicken the liquid.
Corn starch can also be added to baking by replacing wheat flour as corn search is a gluten-free option for celiac people. It is also mixed with other flours to make a crispy batter for deep frying purposes.
