In a medium bowl, using a whisk, beat: eggs, milk, salt, vanilla, sugar, water, flour, and melted butter until well incorporated and smooth. Or combine all the ingredients, pour in a blender or food processor, and blend until the mixture is smooth.
Let the batter rest for an hour or more in the refrigerator or overnight so the crepes can get crispy.
Heat a skillet over medium-high heat, then lightly coat the hot pan with vegetable oil, cooking spray, or clarified butter.
Pour about ⅓ cup of batter, depending on your fry pan or skillet, and start swirling the pan immediately so the batter spreads evenly across the bottom of the pan. Return the excess batter to the bowl. Cook the crepe for 1-2 minutes, until the bottom is light brown. Lift with a spatula, flip over the other side, and cook for about 30 seconds. Remove and place on a plate. Do the same for the remaining batter.
