Last weekend, in Boston, maiden voyage on my first smoker: 4 racks of Saint Louis style ribs. Memphis dry rub and no sauce! I was impressed with the temp control of the Masterbuilt Pro smoker. Very easy to use with propane. Smoked at 225 for 5 hrs. Adding wood (apple) and apple cider spray every hour. Wrapped 2 racks after 2.5 hours. Those were fall off the bone. The ones not wrapped were dry.
