Belgian Waffles - cooking recipe

Ingredients

2 1/4 teaspoons active dry yeast
1/4 cup plus 2 3/4 cups warm milk, divided
3 eggs, divided
3/4 cup butter, melted
1/2 cup granulated sugar
3/4 teaspoon salt
1 1/2 teaspoons vanilla extract
4 cups all-purpose flour

Preparation

In a small bowl, dissolve the yeast in 1/4 cup warm milk. Beat the egg whites just until stiff peaks form. In a large bowl, mix together the egg yolks, 1/4 cup of the remaining milk, the melted butter and the sugar. Add the yeast mixture, salt, vanilla, and then alternate between the flour and remaining milk. Gently fold the egg whites into the waffle batter. Cover the batter without touching it, and then set it in a warm place to rise until it doubles in volume, about 1 hour. Cook in a waffle iron according to manufacturer's instructions.
