Stir together the cornmeal, soda and salt to blend, and then stir into the liquid mixture, blending thoroughly. Pour half the batter into a buttered 23 cm square pan. Spread with the grated cheese, and the onion if used. Cover with the remaining batter, and if desired, sprinkle with more cheese and onion.
