Combine 3 1/4 cups flour with cornmeal, soda water, water, baking soda and salt to form a batter.
Heat your preferred frying oil in a deep pan to 350˚F. Lightly dredge the cheese in 1/2 cup flour, then dip in batter and place gently in hot oil. Cook until light golden brown.
Remove battered cheese from oil and rest on a paper towel to help absorb the oil for about one minute. Serve immediately with spicy marinara sauce, if preferred.
