Heat 1 tablespoon of oil in a large skillet over medium-high heat. Pour 2 to 3 tablespoons of batter into the hot skillet for each corn cake. Cook 3 or 4 cakes at a time, so as not to overcrowd the skillet. Cook the corn cakes for 2 to 3 minutes on each side, flipping when the edges become firm. Keep cooked corn cakes in an ovenproof dish in a warm oven until all the cakes have been made. Serve warm with avocado and your favorite prepared salsa.
