About this dish

Gamja mozzarella hotdog is a Korean street food that skewers a sausage and a mozzarella cheese stick together, coats them in a batter of flour, milk, and baking powder, then presses half-centimeter potato cubes across the entire surface before deep-frying.

The potato cubes cook into a bumpy, golden-brown shell on the outside while the mozzarella inside melts and stretches into long, elastic strands when pulled apart. Sugar in the batter gives the whole corn dog a faintly sweet undertone throughout, and sprinkling additional sugar on the finished hotdog before eating is a common practice at street stalls. Each bite stacks the sausage's saltiness, the mozzarella's creamy stretch, and the crisp snap of the potato crust into one compact, layered structure.

Instructions

Read the steps as a cooking flow: prep, heat, seasoning, doneness control, and finish.

6 steps

1

Step

Dice 250g potato into 0.5cm cubes.

Soak in cold water for 5 minutes to remove excess starch, then drain completely. Moisture on the potatoes prevents them from sticking to the batter.
2

Step

Skewer 4 hot dog sausages and attach 4 mozzarella pieces on top of or alongside each.

Dust lightly with flour - this base coat helps the batter adhere.
3

Season

Combine 1 cup flour, 180ml milk, 1 tsp baking powder, and 2 tbsp sugar to make a thick batter.

The right consistency flows slowly off a lifted spoon.
4

Step

Dip the skewer in batter, then press the diced potato cubes firmly onto the battered surface by hand.

Roll in 1 cup breadcrumbs to coat all sides evenly.
5

Control

Heat oil to 170C.

Add the hot dogs and fry over medium-low heat for 4 to 5 minutes, rotating, until all sides are golden-brown and crispy. The potato cubes need to cook through, so don't rush.
6

Finish

Drain the fried hot dogs thoroughly on a rack.

Serve immediately while the potato coating is crisp and the cheese is warm and stretchy.
