Internal temp? I'm making http://www.food52.com/recipe... and it's a 9 pound pork shoulder that's been in the oven for 13 hours and has reached an internal temperature of 145. I've never cooked one before. Do I pull it out when the internal temperature reaches 160? Or does it need to continue cooking above that temperature to become meltingly tender?
New cooking guidelines from the nationâs food-safety agency confirm Pork Checkoff research that shows pork can be consumed safely when cooked to an internal temperature of 145 degrees Fahrenheit, followed by a three-minute rest time.Pork cooked to this temperature will be juicy and tender. The foodservice industry has been following this pork cooking standard for nearly 10 years.â. The new recommendation reflects advances in both food safety and nutritional content of pork in recent years.
