We found chocolate-drizzled popcorn in Hershey's and Heath varieties tucked on an obscure shelf at Hershey's Chocolate World last week.
The popcorn is apparently made under license by Signature Brands, an Ocala company. The Heath variety tastes like plain caramel corn to me, fresh, but simply sweet with not much of a butter or toffee flavor. The Hershey's Chocolate-Drizzled Popcorn was better (and no tropical oils on the ingredients list!), although it would be more accurate to label it "chocolate-drizzled caramel corn" rather than "chocolate-drizzled popcorn."
Whatever you call it, the popcorn packages are pricy, at $6.95 for 6 oz. — perhaps not a regular family snack, but a lovely gift!
