For each crepe, pour in just enough batter to cover the bottom of the pan, tipping and tilting pan to move batter quickly over bottom. If crepe has holes, add a drop or two of batter to patch. Cook until light brown on bottom and dry on top. Remove from pan and stack on plate. Makes 12 crepes.

Blend until smooth and then continue making the recipe with the rest of the ingredients added to the blender. Cook and serve as normal.
