I have a question in reference to storing pork butts for a benefit. I have been asked to cook for a benefit for the brother of a local firefighter that will be in december. I was just informed that the pork butts will be dropped off tonight in a cooler from the person getting them. Can I freeze them and thaw them later to smoke (I don't know if they are previously frozen at this point but trying to find out) and then freeze cooked chopped pork butt and reheat the day of benefit. I normally vacuum seal and then boil them to reheat with adding juice back in. My understanding is that even if they have previously been frozen, that I am okay as long as temp didn't reach 40 with thawing, to re-freeze them, is this correct?
