A s'more is a confection consisting of toasted marshmallow and chocolate sandwiched between two pieces of graham cracker. S'mores are popular in the United States and Canada, and traditionally cooked over a campfire. In camping, s'mores are a popular treat for many.

Marshmallow is a confectionery made from sugar, water and gelatin whipped to a solid-but-soft consistency. It is used as a filling in baking or molded into shapes and coated with corn starch. This sugar confection is inspired by a medicinal confection made from Althaea officinalis, the marsh-mallow plant.
