Preheat waffle iron.
Mix in large blender bowl
1 c all purpose flour
1 c rye flour
2 T sugar (skip for savory pancakes)
2 t baking powder
1 t baking soda
1/2 t salt
6 T buttermilk powder (optional)
Separately mix in small blender bowl
2 eggs
1.5 c milk (and add up to 1/4c more if it's too thick)
1/2 c greek yogurt [or replace milk and yogurt with 2c buttermilk, and skip the buttermilk powder]
2 eggs
3 T oil
Blend liquids into dry ingredients, mixing just enough to combine decently. Let sit 5min for baking soda/powder to work.
Use 1/2c of mix for a two-waffle iron; cook 4 min by timer.
