Adapted from J. Kenji López-Alt, The Food Lab (W. W. Norton, 2015), Basic Quick Waffles, p. 157, using our buckwheat version of his dry mix.
Ice-cold club soda adds bubbles on top of the baking powder and the whipped whites. That gives a light, crisp waffle with no yeast and no overnight rest. Keep the soda in the fridge until the last second, and cook the batter right away.
Whole-grain flours drink more liquid. If the batter looks thicker than you are used to, loosen it with a splash of buttermilk.
Buckwheat browns fast. The low setting on the iron gives the inside time to cook before the outside goes too dark.
