Use fresh corn if possible for the best texture and sweetness, but frozen or canned corn works well too—just be sure to drain canned corn thoroughly. Don’t overmix the batter; this will keep your fritters light and tender rather than dense and chewy. Maintain medium heat when frying to cook the fritters evenly without burning the outside. For extra crispiness, add a tablespoon of cornmeal or fine polenta to the batter. If you want to make these gluten-free, substitute the all-purpose flour with a gluten-free flour blend. Serve immediately for the best texture, but leftovers can be reheated in a toaster oven or skillet to regain their crispiness.
