So, I am welcoming my cousin back from a trip to Europe by preparing some good old fashion american bbq. I plan to do a 7.5 lbs pork butt at around 225 degrees. I know my family would like to see the pork before I pull it, so I plan to pull it when they arrive at 5pm and eat around 6pm. PLEASE, PLEASE help with the timing. When should I get started in the morning ? I would like to have it rest for 1-2 hours wrapped in a cooler.
