I'm still pretty new to the egg, but I did a pork shoulder a few weeks back following Elder Ward's method (find it on the Whiz's site) and it turned out great. I plan on doing 3 shoulders this Saturday. Question I have is on cook time; the shoulders are 6 to 7 lbs. each so can i still figure on 1.5 to 2 hours per pound based on a single shoulder, or do I need to figure it on 20 lbs. of meat? I know temp makes a difference but I'm thinking at about 250 everything should be done in 12 hours easy. Any thoughts?
