A s'more (alternatively spelled smore, pronounced /ˈsmɔːr/, or /səˈmɔːr/) is a confection consisting of toasted marshmallow and chocolate sandwiched between two pieces of graham cracker.The first known s'more recipe appeared in a "Campfire Marshmallows" cookbook in the early 1920s,[1][2] where it was called a "Graham Cracker Sandwich".[2] A 1956 recipe uses the name "S'Mores", and lists the ingredients as "a sandwich of two graham crackers, toasted marshmallow, and ½ chocolate bar".[10] An additional step may follow, wherein the entire sandwich is wrapped in foil and heated so that the chocolate partially melts.In the UK, the lack of graham crackers is easily improvised with digestive biscuits with a slab of Cadbury's chocolate.
