In a large bowl, whisk both flours, the yeast, and salt. Mix in the milk. Let the batter rest for 1 hour.
Separate the egg, placing the white in a small bowl and the yolk in the batter. Add the melted butter to the batter. Mix until just blended. Whisk the egg white until peaks form. Fold the egg white into the batter.
Heat a griddle or large heavy skillet over medium. Grease the griddle. Working in batches, scoop tablespoonfuls of the batter, spaced 1 inch apart, onto the griddle. Cook until golden brown, 2 to 3 minutes per side. Let cool completely on a wire rack.
