Once the grill is hot, place the ribs bone side down over indirect heat and grill covered for 1 ½ hours. Turn them and grill for another 1 ½ hours, still over indirect heat.
Monitor the ribs occasionally to ensure they don’t stick or burn. After about 3 hours, the ribs should be very tender. If not, grill for up to an additional 30 minutes, aiming for an internal temperature of 145°F.
Move the ribs to direct heat and brush with BBQ sauce on both sides, grilling uncovered for 5-10 minutes before removing.
To Bake Ribs
Preheat the oven to 300 degrees F.
Bake the ribs for 2 ½ hours, checking for tenderness. If needed, continue baking for another 30-45 minutes until they reach an internal temperature of 145°F.
Drain excess fat, apply BBQ sauce to both sides of the ribs.
Broil the ribs for 5 minutes bone side down after basting with BBQ sauce, then brush with sauce a second time and broil until lightly browned and bubbly.
For extra stickiness, broil for a few more minutes.
When ready to serve
Let the rib tips cool for 5-7 minutes, chop them into smaller pieces, and serve.
