i did my first brisket in about 5yrs. I have a Traeger pellet grill. Started it at 10pm and finished at about 7pm the next day. I had only 1 issue during the smoke, I lost heat twice after it reached 150*, figured out that I my auger ran dry almost, won't let that happen again. But here's my question. Why is the bottom of my brisket crispy? I'm thinking that I screwed up when I raised the smoker temp from 225* to 275* for the last 2 1/2 or 3 hrs. Anyone have thoughts on this?
