Preheat your oven to 250°.
Pat your rack of ribs dry with paper towels then season generously with the dry rub of your choice, salt and pepper.
Using a sharp knife poke holes all across the skin side of the rack of ribs.
Wrap the rack of ribs tightly in foil and set them on a rimmed baking sheet or a glass baking dish. This will catch any juices that run out of the foil pack to reserve for the BBQ glaze.
Bake at 250° for 2.5-3 hours.
Remove the rack of ribs and carefully remove them from the foil making sure to reserve the cooking liquid from the foil and the pan.
Turn the oven temperature up to 350°.
Pour the cooking liquid into a small sauce pan and place the rack of ribs back on the sheet pan or glass baking dish.
Brush both sides of the rack of ribs with 1 cup of your favorite BBQ sauce (reserving the remaining ½ cup for the glaze).
Return the ribs to the oven uncovered, meat side up, for 45-55 minutes.
Let ribs rest 15-20 minutes before cutting. While you wait make the BBQ Glaze.
