I've smoked brisket for a few years, some good, some not so good. Here are a few tips i have found:
1. I only season with salt and pepper. But if you ask 10 people you will get 10 different answers as to how to season one.
2. As some has said, don't freak out on the stall. Leave it alone.
3. I like to be around the 225 degree mark. I do the low and slow method. I have seen quicker methods, but i use what has worked for me.
4. Don't time it. A lot depends on the weather, and how windy it is that day. Smoke to internal temp of 210.
5. Wrap at the end in tin foil, a towel and let sit in a cooler. I usually do 2 hours minimum.
i don't wrap, or baste. Some do. Half the fun is finding out what works for you. There are many, many ways to smoke a brisket, ribs, pork butt, etc.
But, most important, have plenty of beer on hand as it takes a long time to smoke one of those baby's.
