What should be added to the grill before placing each pancake when reheating crepes?

To effectively reheat crepes on a grill, maintaining the appropriate moisture and texture is essential. Adding nothing to the grill allows the crepes to warm up without altering their consistency or flavor significantly.

Butter and oil could make the crepes greasy or change their texture, while water may create steam that could lead to sogginess rather than achieving a pleasant finish. By opting to place the crepes directly onto a preheated grill without additional substances, the natural texture of the crepes can be preserved, allowing for a warm and palatable serving without added calories or unwanted moisture.
