*Is potato starch better than flour for fried chicken?
You can definitely deep fry food without a coating—think unbattered chicken wings. But that little bit (or a lot) of extra starchy batter is what makes fried food so appealing. A starchy coating provides a few benefits. Less moisture loss because the batter fries first and seals in most of the liquid, more gentle cooking of the interior food because of this sturdy coating, and just good, old-fashioned mouth appeal. Now, as far as wheat vs potato starch, you’ll find that they both crisp up to the same extent because of their molecular makeup. However, potato starch is quite a bit finer, closer to cornstarch, and lets you create a thinner coating. And thinner means crispier and more delicate.
