how long to cook butt roast on grill
I found this grill method works best with a 4 pound Boston butt shoulder roast, instead of an 8 pound picnic shoulder roast. With an 8 pound roast you are basically getting up really early in the morning to hopefully have the meat done by dinner time.ote that this cooking time is for a 4-pound Boston butt pork shoulder. A general rule on barbecued pork is to cook it at about 215Â°F to 225Â°F for 90 minutes per pound. If using a rub, you'll need to get the rub on the night before and refrigerate.
