Yesterday, Saturday, I asked my husband to take out some pike fillet to thaw, and then I forgot about it. It was around 6 PM. I got home late, had a snack, left a little on the kitchen counter, and went to put the kids to bed at 9 PM, falling asleep with them. I woke up now at 4 AM, feeling a bit restless, and remembered the fish. I thought maybe he forgot. It wasn't in the bowl, not in the fridge, and not in the sink either. Then I saw it – he put it in the microwave!!!!!! I didn't even notice or remember. I'm so flustered... :( Thankfully, it was vacuum-sealed, so it didn't leak. What should I do with it now? Has it gone bad? I moved it to the fridge for now and went back to sleep. Should I refreeze the thawed fish? I don't think that's an option. I wonder if it'll spoil by tomorrow for the cutlets I already planned for the morning?
