What you need:
Pork ribs. Sam's club has three rack for about $20.
Mustard
Seasonings/rubs of whatever type you desire.
BBQ sauce
Pans
Aluminum foil
Oven, grill, charcoal, and wood for smoke if you so choose.
When you're finished you should end up with a pretty large pile of pork. I stuck it in a container to marinate. It's going in the crock pot to make pulled pork for sandwiches.
Next it's time for the rub. I used a very thin coat of spicy mustard on the ribs and then used three separate rubs on the racks. One was McCormick's steak rub, one was Uncle Yammie's, and one was something I threw together with spices at the house.
Then you're going to want to line the pans with aluminum. After that, fill them with about 1/4" water and place the ribs in the pans. Put the pans into an oven preheated to about 200-225 degrees and let the ribs cook.
I cooked mine for about 3 1/2 hours. You want to take them out when they hit about 150 on the meat thermometer. After that, you're almost done.
