I'm looking to smoke a prime rib roast for a large group of people this sat. I have done a few prime ribs but every time I have made them I cooked to temp and rested on the counter uncovered. With this large group these prime ribs are going to have to rest in a cooler and be transported to the event. I am worried that the cooler rest could carry on and overcook these. Any recommendations on a temp to cook to get these to med and med rare with an hour cooler rest? Last thing I want to do is overcook these for my guests. I am looking to cook 2 at Med and 2 at med rare.
