I also will be watching to see how you like the frozen idea. I sure do because it is nice to spread the work out over a couple of days.
Did three butts from the fridge freezer in my post "Three Butts, Three Rubs and Frozen" and it did not make much a difference in time but we think we got more smoke flavor. Need to see squirtthecat's results.
I applied the rub and the injection the day before and put em in the fridge freezer, not the deep freeze, so they were lightly frozen.
