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.

   Serve it warm with a scoop of vanilla ice cream or a dollop of whipped cream—and watch it disappear.
