This started out as strictly a North Carolina-style barbecue, but over the years it has evolved. The rub is more Memphis, and it helps produce a better "outside brown," those prized bits of char that get chopped into pork barbecue. The injected brine is Cuban in influence; injecting pork shoulders is all the rage now, and with good reason. It helps keep the pork moist and get flavor from the inside out.
