Toasted Marshmallow Day is celebrated on August 30th of each year. The staff at National Whatever Day were unable to discover the origin of Toasted Marshmallow Day.
A popular camping or backyard tradition in North America is the roasting or toasting of marshmallows over a campfire or other open flame. A marshmallow is placed on the end of a stick or skewer and held carefully over the fire. This creates a caramelized outer skin with a liquid, molten layer underneath. According to individual preference, the marshmallows are heated to various degrees—from gently toasted to a charred outer layer. The roasted marshmallow can either be eaten whole or the outer layer can be removed and consumed separately and the rest of the marshmallow toasted again.
