Prepare cheese rice cakes, Vienna sausages, and bamboo skewers.

Make small cuts on the sausages and blanch them in boiling water for 30 seconds or pour hot water over them to remove impurities. Drain thoroughly. Rinse the rice cakes under running water and remove excess moisture.

Alternate between rice cakes and sausages as you thread them onto the skewers. Wet the skewers beforehand to make threading easier.

Heat a generous amount of cooking oil in a pan over low heat.

Fry the skewers on low heat until the sausages are golden brown on both sides.

Remove the skewers from the pan and wipe off excess oil. In the same pan, combine ketchup, corn syrup, and soy sauce. Simmer over low heat until the sauce thickens.
