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 ½ 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.
