Step 5: Make the "oven-smoker"
Place the ribs onto the rack in the roasting pan and proceed to wrap the entire package like a present in tin foil. The idea is to create a closed system that will prevent the smoke/steam mixture from escaping. The tighter and more sealed your tent, the stronger the smoke flavor.
I went around the bottom of the pan and looped over the top in a few different directions just to be sure I had a tight seal. See the photo progression below.
