We are told how long to keep things in the freezer and I really don't agree. If it still tastes good after three(plus) years, eat it and enjoy.

I don't know how it could go bad if it has been frozen but if you smell something nasty, toss it.

Most of the freezing guidelines take into account aesthetics, quality, AND safety. Foods dry out, get freezer burn, etc. in the freezer rather than spoil.
If they look, smell, and taste OK, there really isn't a safety issue. I wouldn't use anything questionable to make another product, it would be a waste of time to make something from sub-par ingredients. It wouldn't be a safety issue, but your quality might suffer, even to the point of being unpalatable if they were freezer burnt or something.

Thaw your products, smell, taste, inspect. If they are OK, I wouldn't hesitate to use them in jams.

Thanks y'all. I guess I will do just that. Thaw smell taste and hopefully have enough good stuff to make a batch of jam.
Sandplums, my favorite to jam, did not make again this year. I am desperate for something to can. I have probably 6 gallon freezer bags worth of fruit. If its all good it will be a busy day.
Thanks again
