In a large pot bring water to a boil. Add the spare ribs and turn the heat down to medium and let the ribs simmer for about 20-25 minutes. Drain and set aside.
Put the ribs on a plate and pour about 1/2 of the glaze on them and spread it on both sides with a basting brush.
Grill for about 20-25 minutes, turning every 5 minutes while basting with a clean basting brush and the remaining glaze near the end of the cooking time.
