Insert a bamboo skewer into each half of the hot dogs, leaving about 2 inches of the skewer exposed at one end.
8 hot dogs, 8 bamboo skewers
Place the panko breadcrumbs in a shallow dish.
2 cups panko breadcrumbs
Working with one skewered hot dog at a time, dip it into the risen batter, coating it completely. Then, roll the battered hot dog in the panko breadcrumbs, using a twisting motion as you lift it out of the breadcrumbs. Use your hands to gently press the breadcrumbs onto the batter, ensuring an even coating.
Place the skewered hot dogs in the refrigerator to keep them chilled until ready to use.
In a deep, heavy-bottomed pan or a deep fryer, heat enough vegetable oil to reach a temperature of 350°F (180°C). Carefully add the coated corn dogs to the hot oil and fry for 3-4 minutes, rotating them occasionally with tongs, until golden brown and crispy.
Oil
Remove the fried corn dogs from the oil using tongs or a slotted spoon and place them on a paper towel-lined plate to drain excess oil. While still hot, lightly dust the corn dogs with sugar.
Sugar
Serve the hot and crispy Korean corn dogs immediately, drizzled with ketchup and mustard as desired.
