I have a case of frozen Butts that I was originally going to use to make fresh and smoked sausage from but, it never happened. The USDA recommends 4-12 months storage time. I'm assuming they all have the same date on them of "best if used or frozen by 3-30-13" as the one I just looked at. I realize this is a quality concern and not one of safety. Those of you with experience in this regard.... is there a noticeable difference in quality of the meat within this time frame I'm dealing with? I'm off this week from work and just yesterday plugged in my garage fridge to thaw out these butts for PP. But, if the quality isn't going to be there after they're smoked, I'd rather just go by some fresh meat than waste time. What do you think?
