Marshmallow creme is a uniquely American food item. It is a very sweet, spreadable, marshmallow-like confection. One popular brand of marshmallow creme, sold principally in the Northeast, is Marshmallow Fluff, which was invented in 1917 in Somerville, Massachusetts by Archibald Query and sold door-to-door. Marshmallow Fluff and peanut butter are the fillings of a sandwich, the Fluffernutter, which is popular among young children. The current Fluff factory is located in Lynn, Massachusetts
