Make Fresh Berry Topping and set aside.
Preheat a waffle iron according to the manufacturer's instructions.
Sift the flour, baking powder, and salt into a medium bowl. Set aside.
In a second bowl use a wooden spoon to beat together the egg yolks and sugar until sugar is completely dissolved and eggs have turned a pale yellow.
Add the milk, melted butter, and vanilla extract to the eggs and whisk to combine.
Add the flour mixture to the egg-milk mixture and whisk just until blended. Do not overmix.
In a third bowl, beat the egg whites with an electric mixer until soft peaks form, about 1 minute.
Using a rubber spatula, gently fold the egg whites into the waffle batter. Don't overmix!
Coat the waffle iron with nonstick cooking spray if required and pour enough batter in the iron to just cover waffle grid.
Close and cook as per manufacturer's instructions until golden brown, about 2 to 3 minutes. In checking for doneness, open the waffle iron carefully and watch out for steam. Do not open the waffle iron, though, for at least 1 minute. Repeat cooking with remaining batter. When each waffle is done, remove using either tongs or a fork. Don't forget to turn off the waffle iron when all the waffles are done.
Serve immediately with 1/4 cup of the Fresh Berry Topping spooned over the top of each waffle.
YIELD: Eight to ten 4-inch waffles
