Archibald Query was the inventor of the pasty, sticky, somewhat offensive "creme spread" known as Marshmallow Fluff. The sugar shortage during World War I cost Query his confection. He sold the recipe to H. Allen Durkee and Fred Mower, two candymakers who quickly figured out that combining it with peanut butter creates the "Fluffernutter," which in turn creates sandwich-obsessed mobs of thieving children. The Fluffernutter may soon be the state sandwich of Massachusetts, even though it was almost legally banned from school lunches back in 2006.
Marshmallow was originally used as a throat-coating precursor to the lozenge, but these days it's molded into everything, from cereal squares to baby chickens and moon pies.
This Croque Madame is a fancy, sweet version of a fried ham-and-cheese, made with Nutella and Fluff on cinammon-raisin bread. Yum.
