Lay the pork steaks flat. Pat both sides dry with paper towels.
Heat the oil in a frying pan. Arrange the pork steaks in a single layer. Cook over high heat for about a minute and a half or until the underside is lightly browned then flip to brown the other side.
Mix together the gochujang, soy sauce and sugar. Add half a cup of water and stir.
Pour the mixed seasonings over the pork steaks. Bring to the boil, lower the heat and cover the pan. Cook for 15 to 20 minutes or until the meat is tender and the sauce has reduced to a sticky glaze (the actual cooking time depends on the thickness of the pork steaks).
Serve the Korean-style pork steak with gochujang over rice.
