Alright, looking for opinions and observations on how much weight is lost between raw weight and cooked weight. I have a large cook coming up, well, several smaller cooks actually, and am trying to game plan just how many pork butts I need or get ordered. Cooking for 125-150 people, probably going to shoot for the 150 number, as I don't want to be short. These will be smoked on a 18.5" WSM, 4 at a time - that or I pick up a smoker that my boss has, but is LP fired (an old 270 fuel oil tank), that I'd want to make run on charcoal. It doesn't have any vents in it though, so those would have to be done too... Thinking 40% weight loss 1/3 a person 50 pounds cooked weight 85 pounds raw weight, with 40% weight loss, should equal out to 51 pounds of cooked weight. Does that sound close?
