Loading... Please wait...Fluff Marshmallow - the delicious American spread. Have you tried a fluffnutter ? it's peanut butter and fluff spread on toast or in a sandwich. The origins of Marshmallow Fluff actually go back to 1917. Before WWI, a Somerville MA man named Archibald Query had been making it in his kitchen and selling it door to door, but wartime shortages had forced him to close down. By the time the war was over, Mr Query had other work and was uninterested in restarting his business, but he was willing to sell the formula. Durkee and Mower pooled their saving and bought it for five hundred dollars. Having just returned from France, they punningly renamed their product "Toot Sweet Marshmallow Fluff" but "Toot Sweet" didn't stay on the label for long.
