Some vendors or restaurateurs dip and fry their dogs just before serving.[8] Corn dogs can also be found at almost any supermarket in North America as frozen food that can be heated and served. Some corn dog purveyors sell these premade frozen corn dogs which have been thawed and then fried again or browned in an oven. Premade frozen corn dogs can also be heated in a microwave oven, but the cornbread coating will lack texture.[9][10] Corn dogs may be eaten plain or with a variety of condiments, with mustard being the most popular.[11]
