I'm having people over next week for dinner and have a pack of pork shoulder (individual portions in one pack from Costco) in the freezer. I'm new to cooking and have never cooked any pork product other than bacon. I do have a big Le Creuset french oven that my husband bought me over the holidays. Can I stack the pork shoulder pieces in there and let it cook for a an hour or two? Should I add liquid to the pot? Will it turn out like pulled pork? Any recipes or suggestions on cooking would be appreciated!
