I have done Pork Butts a lot, but never run into this - I've had a butt in the freezer for about 6 months. It was wrapped in three zip loc bags. After thawing and unwrapping, it seemed like it smelled a bit "off". Also seems like I have seen this topic on here before, but I could not locate it.
There is no ammonia smell, just smelled a tick off. I rinsed it, dried it and rubbed it. I was going to put it on tonight low and slow, for the Superbowl tomorrow. Do I need to write this one off and buy a fresh one?
