Mix the milk and the eggs to a smooth batter. Add some milk, in order to make the batter 'runny' (decide yourself when the batter has the right consistency. The runnier the batter is, the thinner the crepes will be). Finally, add a pinch of salt, and -for extra 'fluffiness'- some sparkling water.
In a pan, heat some butter, and -using a ladle- add one portion of the batter to the pan. Bake on one side for a couple of minutes until golden brown, then turn and bake a couple of minutes on the other side as well.
Set aside the crepe, and keep warm. Continue baking more crepes, until the batter is finished. Depending on the thickness of the crepes, this recipe makes for 6 to 8 crepes.
