Two weeks ago, though, Jasmine Listou, the owner of Sugar Lips, debuted the Donut Hole, a turquoise and white trailer that can be hitched to a car and towed around town, making Sugar Lips a new entry in the gourmet mobile-food arena.
Listou has been hauling her new mobile kitchen to her usual stops, taking orders from people who line up at the doorway, then mixing dough and dropping it into the fryer.
Through the curtained windows of the camper, you can watch as the rings, slightly bigger than silver dollars, make their way down her cooking contraption, which employs tiny mechanical arms to flip the donuts and cook them evenly.
Sugar Lips, which has a sister operation in San Luis Obispo, California, also rolled out shaved ice this summer. That way, the hordes of patrons have an option for something sweet that isn't just-out-of-the-oil hot.
