Unlike the American original, most Korean corn dogs aren't made with cornmeal batter at all — vendors use a yeasted, chewy dough, then roll the fried stick in diced potato cubes, panko, or crushed ramen before a squeeze of ketchup and mustard on top.
A sausage — often with a block of mozzarella skewered alongside it — is coated in sticky dough, deep-fried until golden, then rolled in a crunchy coating of choice and drizzled with ketchup, mustard, and sugar. Street stalls fry them to order, stretching the melted cheese for the camera before handing it over.
