If not eating the crepes immediately, cool them on a wire rack first to allow steam to evaporate. If you stack the crepes when they’re still warm, the steam will make the crepes wet (soggy). If you wanna stack the crepes, place a small piece of parchment paper between each crepe. Once cooled, store the crepes in an air-tight container in the fridge for a few days. In the freezer, they will last up to a few months.
