Step 1In a large bowl, sift together the all-purpose flour, wheat flour, cornmeal, salt, cinnamon, baking powder and baking soda.
Step 2In a blender, puree the egg whites, honey, vanilla, buttermilk and melted butter until thoroughly combined, about 30 seconds.
Step 3Gently whisk the dry and liquid ingredients together to form a batter. This makes about 5 cups batter.
Step 4Heat a griddle or large skillet over medium-low heat. Grease the surface, then ladle half-cups of the batter to form each pancake. Cook until puffed and golden brown, about 1 1/2 to 2 minutes on each side.
Step 5This makes 8 to 10 pancakes. The restaurant serves them with butter and maple syrup.
