Tapioca Flour Waffles (4 servings) 2 cups tapioca flour 2 teaspoons baking powder 4 egg yolks - beaten 1 cup milk 4 egg whites Mix the tapioca flour, baking powder, egg yolk and milk in a bowl. In a second, clean and dry metal bowl, beat egg whites until stiff peaks form. Fold into the flour mixture. Bake in a hot, oiled waffle iron until golden brown. This is a basic waffle batter except it uses tapioca flour instead of all-purpose flour. The result is a fluffy waffle with a unique (but still familiar) flavor.
