Preheat the grill.
In a mortar mix all ingredients for the rub: the 3 peppers, cinnamon, ginger, salt and sugar.
Cover the ribs with the rub (the part of the meat) and press with your fingers.
Place the ribs on the grill (bones down and meat up), over indirect heat and cook covered 30 minutes, until a meat thermometer reaches 150°F (ie the ribs are almost done).
With a brush, spread the ribs (only the top) with the BBQ glaze and grill for 5-8 minutes more.
