Hey all, did my 1st set of spare ribs today. Did one with a bbq rub and the other with brown sugar, maple syrup and honey glaze. Smoked them about 4 1/2 hrs @250 mopping evey 50 mins and wrapped for last 1hr of cook time. They were AWESOME! Fall off bone, jucy!! Thanks to you all and the information I found here!!! :-)
