1       c            Water
   1       c            Milk
   3                    Eggs
     1/2   c            Buckwheat flour
     2/3   c            White flour
     1/2   ts           Salt
   3       tb           Melted butter
  Buckwheat pancakes are great, but here's something a
  little more elegant: buckwheat crepes. Serve them with
  melted butter and cinnamon sugar. TO MAKE BATTER IN A
  BLENDER, put all ingredients into a blender jar in
  order given, and blend briefly at medium speed. Stop
  and scrape down the sides of the blender jar; then
  blend for another 5 seconds or so. Pour out the batter
  into a bowl, cover and let rest for 1 hour before
  using. To make batter by hand, beat the eggs slightly,
  add milk, water, salt and melted butter, then
  gradually whisk in flours. Pour the batter through a
  strainer and let sit for 1/2 hour before using. To
  cook crepes, melt a little butter in a crepe pan and
  cook. As buckwheat has an enormous capacity to absorb
  liquid, you might find it necessary to thin the batter
  with more milk or water.
