Mix together dry ingredients, as above. Separate the egg white and yolk. Whisk the buttermilk and egg white together. Whisk together the egg yolk and melted butter, add to the buttermilk mixture and whisk into the dry ingredients just until mixed.
Meanwhile, heat griddle or large skillet over medium-high heat. Brush griddle generously with oil. When water drops splashed on surface bounce and sizzle, pour batter, about 1/4 cup at a time, onto griddle. Leave plenty of space around each pancake. When pancake bottoms are brown and top surface starts to bubble, 2 to 3 minutes, flip cakes and cook until remaining side has browned, 1 to 2 minutes longer. Re-oil the skillet and repeat for the next batch of pancakes.
