I've got time tonight to rub a brisket I'll smoke on Saturday. I typically put on rub 36-48 hours before smoking, but this would be more like 72. I've heard some suggestions that this is ok as long as my rub isn't salt-heavy. I use a variation of the Thrill of the Grill rub recipe, just changing it by doubling the brown sugar and throwing in a little extra cayenne. Salt stays the same and I think is about 1/10th or 1/12th of the rub. Also, I don't brine.
Any suggestions on whether rubbing is ok 72 hours before smoking? Thanks!
