Pineapple Grilled Bbq Ribs - cooking recipe

Ingredients

4 meaty pork rib racks, cut into 3-5 bone sections (depending on cut)
1 whole fresh pineapple
1 1/2 cups brown sugar
2 (18 ounce) bottles barbecue sauce (I prefer Sweet Baby Rays)
1 dash liquid smoke
1 orange, zest of, with remaining orange cut into 1/4-inch slices
1 tablespoon chili powder
1 tablespoon garlic powder
salt and pepper

Preparation

wash the rough outside skin of the pineapple and slice off the bottom and leaves. Cut the skin off in 1/2\"-3/4\" slices. Set the remaining pineapple aside.
In a large stock pot (15 qt is best), add the pineapple skin slices, 1 cup brown sugar,2 cups BBQ sauce, the orange slices, dash of liquid smoke, and the rib sections.
Add enough water to the pot to cover the ribs completely, and bring to a boil. Reduce heat and simmer ribs for 40 minutes. Don't overcook them.
Remove ribs from pot and set aside to cool.
While ribs cool, make a rub from the orange zest, remaining brown sugar, chili powder, garlic powder, and salt and pepper to taste.
When ribs are cool enough to handle, apply rub to both sides of meat. Place ribs in a plastic freezer bag, and allow to marinate for 3 or 4 hours (or longer if you prefer).
After marinating time, add 1 cup of BBQ sauce to the bag and coat ribs. Allow them to come to room temperature in the bag.
In the mean time, slice the remaining pineapple into 1/2\" thick rings and brush with BBQ sauce. I occasionally add a tsp of honey to the BBQ sauce for grilling --
Heat BBQ grill to 300 degrees. Place ribs on grill, and brush with BBQ sauce, turning frequently and basting with sauce, about 20 minutes, being careful not to let sauce burn. Reduce heat if necessary.
During the last 8 minutes of cooking, add the pineapple slices to the grill, turning once and allowing them to carmelize and brown with grill marks.
Remove ribs and pineapple to a serving platter and enjoy.
