For good baby back ribs, I trim any excess or hard fat and any hanging meat, then pull the membrane fron the bone side. Slather both sides of the rack with plain mustard and sprinkle with Jeff's rub. Put on the smoker, naked for about 3 hours @ 250-275*. After 3 hours, check for a bend. If you have a decent bend and some pull back on the bones, they are mostly done. I then sauce/ glaze mine with 2 parte Jeff's sauce, 2 parts honey and 1 part apple juice. Heat this in a pan to a good spreadable consistency. Do this twice for 15 minutes. Take the ribs off and let them rest on the counter for about 30 minutes or as long as you can stand it, then slice and serve.
The recipes for Jeff's sauce and rub are available for sale here. The recipes are ver user friendly and can be tweaked to your personal taste. More or less heat and more or less sweet. The proceeds from the sale are used to support and maintain this great site.
Good luck and good smokin', Joe
