Make the popular street food at home. This recipe shows you how to create the half-and-half corn dog (half hot dog, half mozzarella) with two crunchy coating options: classic panko or diced potato (Gamja style). Achieve the perfect gooey cheese pull and crispy exterior.

Ingredients

Scale
  • 6 wooden skewers
  • 6 small hot dogs or cocktail sausages
  • 6 mozzarella sticks (low moisture, about 3 inches long)
  • 1 cup all-purpose flour
  • 1 teaspoon baking powder
  • 1/2 teaspoon salt
  • 1/4 teaspoon black pepper
  • 1 large egg
  • 3/4 cup cold water
  • 1 cup panko breadcrumbs OR 1 cup finely diced raw potato (for Gamja style)
  • Vegetable oil, for deep frying
  • Granulated sugar, for dusting

Instructions

  1. Prepare the fillings: If using the half-and-half style, cut the hot dogs in half lengthwise. Skewer one piece of hot dog and one mozzarella stick onto each skewer, ensuring the mozzarella is centered. Freeze the skewered items for 30 minutes to help them hold shape during frying.
  2. Prepare the batter: In a medium bowl, whisk together the flour, baking powder, salt, and pepper. In a separate small bowl, whisk the egg and cold water. Pour the wet ingredients into the dry ingredients and mix until just combined. Do not overmix; a few lumps are fine.
  3. Prepare the coatings: Place the panko breadcrumbs or diced potatoes on separate shallow plates.
  4. Coat the corn dogs: Remove the skewered items from the freezer. Dip each skewered item completely into the batter, letting excess drip off.
  5. Apply the crust: Immediately roll the battered item in the panko or press the diced potatoes firmly onto the batter until fully coated.
  6. Rest the corn dogs: Place the coated corn dogs on a parchment-lined tray and let them rest at room temperature for 15 minutes. This helps the batter set before frying.
  7. Heat the oil: Pour 2 to 3 inches of vegetable oil into a deep, heavy-bottomed pot or Dutch oven. Heat the oil to 350°F (175°C). Use a thermometer to monitor the temperature.
  8. Fry the corn dogs: Carefully lower 2 to 3 corn dogs into the hot oil, ensuring you do not overcrowd the pot. Fry for 3 to 4 minutes, turning occasionally, until the coating is deep golden brown and crispy. If using mozzarella, fry just until the outside is crisp; do not overcook, or the cheese will leak out.
  9. Drain: Remove the corn dogs with tongs and place them on a wire rack set over a baking sheet to drain excess oil.
  10. Finish and serve: While still hot, roll the corn dogs generously in granulated sugar. Serve immediately with your choice of sauces like ketchup, mustard, or mayonnaise for a sweet and savory snack.

Notes

  • For the best cheese pull, use low-moisture mozzarella sticks. High-moisture cheese releases too much water when heated.
  • If you want a slightly chewier batter, substitute 1/4 cup of the water with milk.
  • Maintain the oil temperature strictly between 345°F and 355°F. If the oil is too cool, the coating will absorb too much oil and become soggy.
  • If you are making the potato crust, ensure the potato pieces are very small and uniform for even cooking.
