I saw some Boston butt pork roast on sale for $1.19/lb and thought I would get some for one of my first 5 smokes once my WSM gets here on Tuesday. I noticed that the recipes included on this WONDERFUL site reference q'ing two roasts at once. There is only two people here and doing two would be overkill without company. Can I follow the instructions provided with just doing one? Or do I need to change temperatures of the cooker, etc, if only doing one. Thanks.
