Start by dusting each tomato slice in the remaining plain flour. Dip them into the egg-buttermilk mix, letting the extra drip off. Then press them into the seasoned cornmeal until coated all over.

Heat 1/4 to 1/2 inch of vegetable oil in a large cast-iron pan to 375°F. Add the coated tomato slices gently, a few at a time, so the pan doesn't get crowded. Cook each side for about 2 minutes, until crispy and golden. Lay the fried tomatoes on paper towels or a wire rack to drain oil. While still warm, give them a little sprinkle of salt for extra flavor.
