They're baaaackk!! By popular demand after a successful run last year Doritos is bringing back Classic Ketchup and Spicy Mustard Doritos this summer! They will be available through July and should be on your local grocer store shelves now. The Ketchup flavor, according to the Doritos brand, "is based on Canadian-style ketchup with a tangy and subtly sweet taste" and the spicy Mustard flavor "draws inspiration from Chinese hot mustard to deliver a big kick to the taste buds".
