I bought a Sainsburys breast/crown of chicken with pork and sage stuffing a few days ago. It's dated the 15th July so thought I need to use it tonight. I've just opened the film and there is a smell, it's not overpowering, or rancid but it does have a weird smell. Maybe it's the pork stuffing? It's been stored at 4 degrees in fridge, it's not been out on counter and the film was intact. It takes 60 mins to roast. I've put it on oven but I'm not sure if I'm brave enough to serve it as the date was today. The smell wasn't overpowering but present. What would you do?
