So I'm trying foiling midway for the first time right now. The reason being that I heard it could ease the "stall" and speed cook time. You see last week, I started a butt a little over 6 pounds at about 8 am, thinking it would be ready by dinnertime. That sucker didn't hit 195 until like 10pm! So this morning I put a butt on that was about 6.25 pounds. Put it on around 6:45 and smoked it for about 4 hours. Once it hit 160, I took it off, foiled it, and put it back in the smoker. (I use the red ECB.) It's now a little after 1, so about 6 1/2 hours total cook time, and it's already reading 198. I am using a remote probe thermometer, that I didn't take out even when foiling. If this is a true temp, this thing'll be done by 2 pm for a cook time a little over 7 hours. Wow. Does foiling really make that big of a difference? If so, I think I've been converted. I want to easily be able to smoke for parties and such, but I've been reluctant because cook times have been really hard to gauge accurately.
