Combine milk, water, ACV and Beetroot crystals. Whisk and set aside.
In a separate bowl combine dry ingredients, whisk, and set aside.
Add flax and wet to dry ingredients and mix gently. The buckwheat flour soaks up A LOT of moisture. At this time you might need to add 1/4c-1/2c more liquid. I added water until I was happy with consistency. Too thin, and it will run, too thick and it won’t spread.
Heat waffle iron.
Add in a heaping ladle of batter to waffle iron. Once cooked, transfer to a wire rack in a preheated oven while you make the rest of the waffles. I yielded 4 large round waffles from this recipe.
