I bought a load of chicken breasts at the start of lockdown. What was that, just over three months ago? Took some out earlier this week to defrost - just left it on the side between two plates so the sun couldn't get to it etc. Just went to cook it and the stuff looks a bit ropey. Should be fine though, I mean it lasted months in the freezer so it should be fine being out for a few days. Right? I haven't touch or moved it so there's no way it could have gone bad!
