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.

   Instead of the classic deviled egg filling (which uses mayo or mustard), mashed avocado steps in to add healthy fats, a subtle buttery flavor, and a lovely green hue.
