A while back I smoked a brisket and it came out like leather. Ended up in the garbage. I did not brine it first and it cooked for about 8 hours in the smoker. Temperature was around 200 with a electric smoker. My wife now informs me that there is another half to the brisket that we did not cook. Should I waste my time cooking it or throw it out? Also if I should cook it is there a way to give me a better chance that it will be tender.
