In a large bowl, whisk all dry ingredients together until well combined. Create a well in the center and add in the egg, butter, and water. Whisk well to create a mostly lump-free batter. If the batter is too thick for your liking, add in more water. If the batter is too thin, add more flour.
Fry on a lightly buttered nonstick skillet over medium-low to medium heat until golden brown on both sides.
