Before you start

Before starting, ensure all ingredients are measured and ready. Cut the mozzarella into uniform thick sticks and prep the beef frankfurters. Parboil the potato cubes until just tender but still firm, then pat them dry completely.

Prepare the frying station by heating the oil in a deep, stable pot and keeping a thermometer handy to monitor the temperature throughout the cooking process.

Ingredients at a glance (12)
  • 4 blocks low-moisture mozzarella cheese, cut into thick sticks
  • 4 beef frankfurters
  • 1 cup all-purpose flour
  • 2 tbsp sugar
  • 1 tsp yeast
  • 1 egg
  • 1/2 cup warm water
  • 1 cup tiny parboiled potato cubes
  • 1 cup panko breadcrumbs
  • 4 cups vegetable oil, for deep-frying
  • Granulated sugar for serving
  • Ketchup and spicy mayo for serving

Instructions

Preparation and Batter

  1. Prepare the skewers
    Thread the blocks of mozzarella cheese and beef frankfurters onto wooden skewers. Ensure they are secured firmly on the sticks, then place them in the freezer to chill until they are cold and firm to the touch.
    Look for The cheese and meat should feel firm and cold, indicating they are ready for the batter.
    Tip Chilling the skewers helps the batter adhere better and prevents the cheese from melting too quickly during frying.
  2. Create the batter
    In a tall glass, combine the flour, sugar, yeast, egg, and warm water. Whisk the ingredients together thoroughly until the mixture forms a thick, stretchy, and smooth batter consistency.
    Look for The batter should be thick enough to coat the back of a spoon without running off immediately.
    Tip Ensure the water is warm but not hot to activate the yeast without killing it.

The skewers are cold and firm to the touch. The batter is whisked into a thick, stretchy consistency that clings to a spoon. The oil is heating, and the coating station with potatoes and panko is ready for the dipping process to begin without delay.

Coating Process

  1. Coat the skewers
    Dip each prepared skewer into the batter, ensuring the cheese and frankfurter are coated completely. Immediately roll the sticky battered skewers in the tray of tiny parboiled potato cubes, then dredge in panko breadcrumbs until every gap is fully covered.
    Look for The surface should be completely covered in a mix of potato cubes and panko breadcrumbs.
    Tip Press the potato cubes firmly into the batter to ensure they stick during the frying process.

Each skewer is evenly coated in the thick batter, then thoroughly covered in the potato cubes and panko breadcrumbs. The surface of the corn dog is textured and uniform, with no large gaps where the batter might leak. Everything is ready for immediate immersion in hot oil.

Frying and Finishing

  1. Deep fry the corn dogs
    Heat the oil in a deep pot to 350°F (180°C). Carefully lower the skewers into the hot oil. Deep-fry for five minutes until the potato cubes turn golden-brown, blistered, and shatteringly crispy. Ensure the internal temperature of the frankfurter reaches 145°F (63°C), and let rest for 3 minutes.
    Look for The corn dogs are ready when the exterior is a deep golden-brown and the potatoes are crispy.
    Safe temperature 145°F (63°C) internal temperature (steaks, chops and roasts)
    Tip Fry in small batches to maintain the oil temperature and ensure even cooking throughout.
  2. Finish and serve
    Remove the fried corn dogs from the oil and let them drain briefly on a wire rack or paper towel. While still hot, roll each corn dog in granulated sugar, then drizzle with ketchup and spicy mayo before serving.
    Look for The sugar should lightly coat the surface, and the sauces should be applied in thin lines.
    Tip Serve immediately while the cheese is still melted and the exterior is hot and crunchy.

The corn dogs have reached a deep, blistered golden-brown color. The potatoes are shatteringly crisp, and the internal temperature of the frankfurter is 145°F (63°C).

They are drained, coated in sugar, and drizzled with sauces, ready to be served immediately while the cheese is still perfectly melted.

Common mistakes

Avoid overcrowding the pot during frying, as this causes the oil temperature to drop rapidly, leading to greasy, heavy corn dogs rather than crispy ones.

Ensure the skewers are thoroughly chilled before dipping; if they are at room temperature, the batter may slide off before it has a chance to set in the hot oil. Always pat the parboiled potatoes dry to prevent splattering.

How to tell it’s done

The corn dogs are done when the exterior reaches a deep, uniform golden-brown color and the potato cubes are crispy.

Using a thermometer, verify the internal temperature of the frankfurter has reached 145°F (63°C) to ensure it is thoroughly cooked. The cheese should be soft and elastic when pulled, which happens as the internal heat conducts through the center.
