fatties are chubs of breakfast sausage, left whole, smoked. the majority like jimmy dean. i prefer the jimmy dean sage. doesn't need a rub or mop, but feel free to do it if you so desire. the hot flavor it good too. the heat smokes out of it. i like to throw on a 5 pack of polish sausage links too. my wife prefers them over fatties. she eats the polish and i eat the fatties. on the fatties, smoke for 1.5 hours, flip, and smoke another 1.5 hours. do the polish the same way.
