In a large mixing bowl, whisk together the flour and eggs.
Gradually add in the milk and water, stirring to combine.
Add the salt and melted butter; beat until smooth.
Let the batter rest for at least 30 minutes at room temperature or refrigerate for up to 1 hour.
Heat a lightly buttered non-stick skillet or crêpe pan over medium-high heat.
Pour about 1/4 cup of batter into the pan for each crêpe. Tilt the pan in a circular motion to evenly coat the surface with the batter.
Cook the crêpe for about 1-2 minutes, until the bottom is light brown. Loosen with a spatula, turn and cook the other side.
Sweet: Nutella, fresh fruits, whipped cream, chocolate sauce, honey, powdered sugar.
Savory: Ham and cheese, sautéed mushrooms, spinach and ricotta.
