A mystery in the world of desserts, Blue Moon is an unusual, smurf-blue colored, sweet ice cream that tastes different to everyone who has ever tried it, and to make matters worse, its ingredients are trademarked and heavily guarded. There is a huge list of possible flavors: vanilla, lemon, pistachio, coconut, almond, marshmallow, bubblegum, pineapple, ginger, cotton candy, blue curacao, licorice, berries, or Froot Loops with milk.
Its flavor might be a mystery, but so are its origins. There are two theories - one claiming that the ice cream was invented in the 1940s or 1950s in Milwaukee, and the other places it in Michigan, crediting the Sherman Dairy Products company in South Haven.
