Old-fashioned waffles

• 4 eggs (separated)
• ½ cup butter (melted and slightly cooled)
• 1 teaspoon vanilla 
• 1 tablespoon sugar
• 2½ cups milk
• 3 cups flour
• 2 tablespoons baking powder
• 1 teaspoon salt 

Directions

In a mixing bowl combine all dry ingredients (flour, baking powder and salt) and set aside. In a separate larger mixing bowl, whisk egg yolks. Add milk, melted butter, vanilla and sugar and continue to whisk. Add sifted dry ingredients to egg mixture and gently stir until combined. Do not overmix. Using an electric mixer, beat egg whites until stiff peaks form. Using a rubber spatula, fold in egg whites until combined. Spoon batter into a stove-top waffle griddle or non-stick electric waffle griddle (according to griddle directions). Top off with fruit preserves or maple syrup.
