Cut the spareribs into individual ribs if you didn't ask a butcher to.
In a large skillet, heat the corn oil on medium high heat until nearly smoking. Add the ribs and brown on each side, about 2 mintues per side.
While the ribs brown, wisk together remaining ingredients and pour over the ribs. Turn heat down to low and cover. Cook for 40 minutes, turning the ribs every 10 inutes or so.
