Cold Stone Creamery

Founded by ice-cream enthusiasts Donald and Susan Sutherland in 1988, Cold Stone Creamery has grown to more than 1,400 locations across North America. Each day, the shop's scoopers mix up fresh batches of ice cream, sorbet, and yogurt, which are served by the scoop, piled high in sundaes and fresh-made waffle bowls, and blended into shakes. After customers choose their desired flavor, the staffers toss the chilly goodness upon a slab of frozen granite and fold in a smorgasbord of candy, nuts, and fruit to achieve the ideal ice-cream-to-add-in ratio. Customers can dream up their own creations or opt for a Signature Masterpiece, sampling one of more than 11.5 million possible flavor combinations, which still await a brave conqueror to unlock them all.
