Mix together the apple cider vinegar and milk. Let the mixture rest for a few minutes, until curdled. Gently whisk in the remaining wet ingredients. Then, add the dry ingredients and whisk just until combined.Pour a ¼ cup of batter onto a hot oiled griddle or skillet. I use this griddle.Watch the sides of the pancakes. They should thicken and the tops begin to bubble. This is the sign it's time to flip. Flip and continue to cook a couple of minutes.Transfer to a warm oven (I put mine on 175F, the lowest temp and then turn off) until ready to enjoy.Serve warm with pure maple syrup, raw honey, nuts, fruit, and/or butter.
