Alright I was asked to cook for 200+ for a reunion and have absolutely no idea how much pork loin or butt to get to feed these people any input would be greatly appreciated..
I would spend some time perusing the catering and cooking for the masses forum posts going back a few months. Lots of help there'
Pork loin, I assume you mean boneless, you can figure 3/4 lb uncooked (or 2/3lb brined, uncooked), pork butt, bone-in, I would go with Paulie's number. Are you not going to offer something other than pork? With 200 people, they may be some non-pork eaters.
allrecipes.com/ according to this site it would take 50lb of pork butt, I have use this site before , great web site they give you the receipe and auto figure it for you
