I'm catering my own wedding. I will cook the Pork on a BBQ trailer three days prior to the wedding, then freeze it, then thaw (add JJ's finishing sauce) and serve with BBQ sauce on the side. My question is, should I use Pork butt or save some money and buy Pork cushion? The difference in cost isn't huge per pound, but when you're cooking for 200 people every little bit helps.
