How many pounds of pork shoulder to feed 100 people?
70 lbs uncooked, 50lbs of cooked meat. Typically you should plan on 1/2 pound of cooked meat per person. However, the pork shoulder will lose weight while it's cooking, so you'll need to purchase around 70 lbs of meat. A pound of meat will feed 1 and 1/2 guests and make 3 good sized sandwiches.
