Gluten-free, Dairy-free Waffles

In our search for gf breakfast foods, I found these fantastic gf waffles! I used the flour mix suggested of 2 cups White Rice Flour, 1 cup Potato Starch, 1/2 cup Tapioca Starch, 1-3/4 tsp Guar Gum, and have also subbed in some brown rice flour. With our changes:

Gluten-free waffles

Whisk together
1 cup white rice flour
1 cup brown rice flour
1/2 c millet flour
1 c potato starch
1/2 c tapioca starch
2 tsp guar gum
3/4 tsp salt
2 TB baking powder
1 TB sugar

In a separate bowl, beat to soft peaks
4 egg whites

In a separate bowl, beat together
4 egg yolks
3 cups milk (we've used rice, almond or soy)
1/4 c oil
1 tsp vanilla

Add dry ingredients to wet, reserving the egg whites. Blend and let stand for about ten minutes.
Using a rubber spatula, combine egg whites. Bake on waffle iron. In our four square belgian waffle iron, the recipe makes about 20 squares (or five rounds on the iron).
