6-7 pounds of boneless pork shoulder from Costco - first time I've tried their large shoulder cryovac pack. Injected and marinated in Yoshida gourmet sauce for 24 hours, then slow cooked at 250 deg F grid temp to 195 deg F. I did not use any rub.
It's in foil now but I snitched a taste before I wrapped it up. Initial impressions: tastes like pork with a very subtle hint of teriyaki flavor. I will probably use rub if I do this again.
