2 large eggs, separated
1 cup buttermilk
2 tablespoons melted butter
1 cup cake flour
1 tablespoon sugar
1/2 teaspoon baking powder
1/2 teaspoon baking soda
1/4 teaspoon salt
1. Whisk the egg yolks into the buttermilk in a medium mixing bowl. Whisk in the butter. Put the flour, sugar, baking powder, baking soda, and salt into a sieve and sift into the buttermilk. Lightly whisk until the batter is just mixed (a few lumps won't hurt).
2. Put the egg whites in a clean mixing bowl and beat with a whisk until soft peaks form. Use a rubber spatula to fold them into the batter. Don't overwork the batter, keep it light and fluffy.
3. Pour a little oil onto a nonstick griddle or large skillet. Wipe out the oil with a paper towel, leaving only the thinnest film. Heat the griddle over medium- high heat until hot. Pour about 1/4-cup of batter on the griddle. Cook until little holes appear on the surface; lift the edge to check that the cooked side is golden brown, about 1 minute on each side. Slather on the butter and a few good glugs of real maple syrup.
