I'm helping host a craft beer tasting party and have been asked to provide pulled pork sandwiches. I plan on smoking Boston butts but am wondering about how much to get. I have an MES 30" and 40" and have access to a buddy/neighbor's 40". We are expecting 60 men to attend the party. Was thinking of serving pulled pork sandwiches on white bread, different BBQ sauces, pickles, onions, and a couple of sides (potato salad, cole slaw, etc.). Does anyone have a recommendation on how many pounds of meat I should get? Obviously, I'd like all the cuts to be around the same size (I was thinking 8 to 10 pounds each), so that I can time everything right. And obviously I'll end up discarding some of the more fatty, inedible pieces of meat as I pull it... I'm guessing 25 to 30%. Any help would be appreciated.
