Place all liquid ingredients into a blender, and pulse to mix. Alternately you could whisk together dry ingredients in a bowl first, followed by the liquids.
If using a blender, Sprinkle in all the dry ingredient and blend briefly, but thoroughly to mix.
Either way, let the batter rest for 2-4 minutes to give the the flours time to 'drink' some of the liquids...it will thicken a bit.
You get to play with the final thickness...some like their pancakes thick, others like them thin, play around with liquid/flour ratio to your liking.
