My plan for this weekend was to try out my new enamel/cast iron dutch oven by making the Roasted pork shoulder with salsa verde that was recently referenced from the LA times (8 to 10 hours cook time). Saturday I am busy so Sunday I was going to get up early and get it started. But my Nonna has summoned me to her house for a few hours on Sunday for a birthday party. What harm would come from leaving the pork in the oven at a low temp of 200 or so? Does anyone else ever do such a thing?
