Combine flour and salt into a bowl; form a well and put slightly beaten eggs and melted butter into it.
Beat with a wire whip or blender to form a smooth paste.
Gradually add milk and beat until large bubbles form.
Let batter rest one hour so flour is absorbed.
Use a crêpe maker or pour 1/4 cup of batter onto a hot griddle. Cook two minutes, flip and cook the other side.
