I'm thinking it will have to have been braised, cooled in its liquid, and reheated.
so the juices will no longer be so drippy.
Heck, I'm bluffing. I've never braised a brisket in my life, and here I am catering a Jewish funeral?
My mom used to put a brisket in the Crock Pot with a bottle of ketchup and a bottle of beer, cook it for days, it seemed, and serve the resulting fallen-apart stuff on brown 'n serve rolls. I may just go that route.
