In a large bowl, combine the flour and salt. Create a well in the center and add the eggs. Gradually whisk the flour into the eggs, then slowly pour in the milk while whisking until you achieve a smooth batter. Add the melted butter and sugar, whisking again.

Let the batter rest for about 10-30 minutes.

Place a non-stick skillet or crepe pan over medium heat. Lightly grease with a little butter or oil.

Pour about ¼ cup of batter into the pan, quickly tilting it in a circular motion so the batter spreads evenly across the bottom. Cook for about 1-2 minutes, or until the edges begin to lift and the bottom is golden.

Use a spatula to gently lift and flip the crepe. Cook for another 1 minute, then transfer to a plate.

Repeat the process, stacking the cooked crepes on a plate. Serve warm with your favorite fillings!
