In a large bowl, whisk together cornmeal, flour, baking powder, and salt.

In a separate bowl, whisk together buttermilk and egg. Pour into the dry mixture and stir just until combined. The batter should be thick but pourable — if it’s too dry, add a splash more milk.

In a cast-iron skillet, heat ¼ inch of oil or bacon grease over medium heat until hot but not smoking (around 350°F / 175°C).

Drop spoonfuls of batter into the skillet, flattening slightly with the back of a spoon. Fry for 2–3 minutes per side until golden brown and crisp.

Transfer to a paper towel-lined plate to drain. Serve warm and enjoy immediately!
