Season ribs with salt and pepper and place on baking sheet. Cover with foil and bake for 90 minutes. Uncover and drain any excess liquid from the pan. Raise the oven temperature to 350 degrees.
Set aside a little barbecue sauce and brush the ribs with that; place the pan back in the oven. (You will be brushing barbecue sauce on meat that's not fully cooked, so do not put the used brush into fresh sauce unless you are using it all.) Bake, uncovered, for 30 minutes. Set aside some more barbecue sauce. Turn the ribs over and brush with more of that sauce. Bake for another 30 minutes.
Set oven to broil and set aside some more sauce. Brush the ribs with that sauce and broil them, 6 inches from the heating element, for 4 to 6 minutes, turning once, until the ribs are charred in places. Remove from oven.
Add 2 tablespoons of bourbon to the remaining sauce. Using a clean brush (because you are done cooking), brush the ribs with sauce and serve with extra sauce on the side.
