Waffles

I got this recipe from a friend. I haven't tried it yet, but they assured me these are the best waffles ever.
1 c. white flour
1 c. wheat flour
3 tsp. sugar
1 tsp. salt
1/2 tsp. baking soda
1 tsp. baking powder
mix together
3 eggs
4 Tbsp. melted butter
2 c. buttermilk
Mix just until combined. The batter will be very lumpy. They also said to use real buttermilk and not the milk and lemon trick. It makes a big difference.
