The unique cold treat can be enjoyed by itself, in a shake or the ever popular concrete. The Polar Crunch concrete, a mixture of custard, heath bar, butterscotch, and pecans, is a fan favorite. For a taste of the South, try a Southern Delite Specialty Sundae. Start with custard, then add peaches, strawberries, and bananas. Top with whipped cream and a cherry and you have yourself quite a treat.
