I do more trimming to briskets than I do to my pork butts, so now I just trim butts at the comp. Briskets I'll put into foodsaver vacuum bags.
When I was trimming butts at home, they also went into the vacuum bags. But I would run into problems where the butts were so big that it made it real hard to get all the air out.
One day I'll get a 15" sealer so my life can get easier!
