When I did my first smoke, I got a 5lb brisket from a local grocery store, it came in a cryovak pack so I blotted it somewhat dry before putting the dry rub on it. I thoroughly covered it with rub, worked it in well and then put it in an aluminum roasting pan in the fridge for the night. The next morning I opened the fridge and discovered that my dry rub had turned in to... sludge? There was a good amount of liquid in the bottom of the pan and the rub was sludge. The end result was good, but I wondered if shouldnt have put a rack in the pan to elevate the brisket from the liquid. Or should I just plan better and get my brisket from a butchers shop that isnt cryovack'ed in liquid? Since it turned out well, should I just keep doing what I did before or change things up?
