Given the background description of some cooking related query, summarize the question into a title

Ex Input:
I made a sauce with frozen rhubarb and raspberry mixed with sugar and reduced it until there is hardly any juice left. I put the leftovers in a sealed container in the fridge. Would this still be good? Is there anyway to tell when this is going bad?

Ex Output:
How long does a fruit and sugar mixture last?


Ex Input:
I got out some wild sockeye salmon that had been in the freezer for quite a while (several months at least, not more than a year). It was vacuum-packed, no freezer burn, sealed properly, etc. I cooked it very well but while it smells and looks okay it tastes earthy and a bit undercooked (even though it's flaky and opaque). The texture is fine. I stopped eating it but wondering what this is about. I cut it in half while it was still raw and washed the knife and then used it for salad ingredients. If the knife wasn't washed well enough could the raw salmon cause me a problem? Thanks!Edit: Does anyone know what the taste might mean? Or if it might mean it's not really edible? I did eat a bit and am fine but I guess we have taste buds for a reason so I should probably avoid it. I am curious as to what might have gone wrong.

Ex Output:
Earthy tasting frozen salmon


Ex Input:
Raw fish pieces have stuck to each other in freezer. How to take out few pieces of fish without disturbing other pieces?Thawing whole bunch may not make sense since I do not intend to eat them all today. What are my options?My question is about "how" to do it. Should I hammer out the pieces without thawing them? If yes, then what would be the approach to do it?https://cooking.stackexchange.com/a/40690/6168 Quick and sloppy:  Pry the frozen fillets apart using a case knife or use a wedge of some sort to separate them physically without thawing.Why is this method called sloppy? What is wrong with it?
