I started these two 8# shoulders just before 1pm, & we're now at an IT off 180 even though I've been rolling at 250-275 all day according to my iGrill 2. I tested the temp with my Thermapen as well to make sure, & it was identical. Looks like I'm going to be in for a late night since I have to pull it and vacuum seal it tonight. Church is going to come early in the morning, but I hope everyone likes lunch tomorrow. I used Jeff's rub on the meat & Royal Oak lump, pecan, cherry & apple in the pit, & I'll be topping it off with a finishing sauce once it's pulled. I'll post finished pics if I have time tonight.
