Question: how much pork shoulder for 20?
Answer: For pulled pork, the standard rule of thumb is one-third to one-half pound of meat per person. When cooked and shredded, a bone-in pork shoulder will lose around 40 percent of its weight. For example, a raw 10-pound pork shoulder (or two 5-pounders) will yield about 6 pounds of finished meat, serving 12 to 18 people.
