I'm still looking into long Butt cook times. Done 3 yesterday in 08, all close to 8* Two took 21 + hours & the one on the top shelf took 23 hrs & 50 min.I made sure they did not touch the back or side walls. They were all very good & moist when pulled. These were the longest cooks yet. I measured the internal box temp & was over 220* , so I think thats ok. The thing i did notice was the butts had a very thin fat cap & the catch pan under the smoker had very little liquid in it when the cook was done. I have had quicker cooks where the catch pan was overflowing. Do you think the length of a cook is proportional to the amount of liquid injected by the processers & the amount of fat on the Butts??
