In a bowl, whisk the egg with the buttermilk. Separately, combine the flour, cornmeal, sugar, baking powder and salt. Combine the dry and wet until a dough forms.
Heat a frying pan to medium heat with oil just covering the bottom of the pan. Drop a little of the batter in to see if its frying. It should sizzle very gently. Give each cornbread at least an inch from the other one.
Add dollops of the batter into the oil and when you notice the edges getting golden flip the cornbread oven and press it down with a spatula. Allow to finish cooking through the middle and making the opposite side golden before removing.
Allow to cool for a minute before serving and enjoy.
