Bought a large bone in pork butt yesterday to cook today. It was cryovac wrapped and had 3 weeks left till date. When I opened it this morning I noticed a “unusual smell” not like spoiled but just a faint odd smell. At first I was going to toss it but convinced myself it was just raw meat smell. Went ahead and injected with apple juice and ACV, and rubbed it down and put in the smoker. As it cooked there was that smell again. Stronger now. Had just about decided to toss it. Finally finished so I pulled it off and carried it inside. Now it smelled perfectly normal. I asked my wife to come take a whiff. She said it smelled normal to her and picked up a piece and ate it. Tastes great She said and walked away. I picked up some and tasted it. Tasted fine. Actually great. We ate sandwiches for supper. I guess we will know soon.
