Corn dogs are one of America's most iconic fairground foods. The combination of a juicy hot dog wrapped in a crisp, golden cornmeal batter became popular at state fairs and amusement parks during the mid-20th century. This version uses kefir, which gives the batter a slight tang and helps create a light, tender coating.

   Feel free to adjust the ingredients and seasonings to your taste. Some variations include adding pickles, capers, or using a different type of mustard.
