So I'm not a caviar eater, but received a small jar in a gift basket 2 years (!) ago. I put it in my panty and forgot about it. Just came across it today and am wondering if I can still serve it. It doesn't seem to be pasteurized. I looked it up online and it's not an expensive or rare caviar by any means (Capelin caviar from Iceland). I did some quick research and it seems that caviar should be served within a few weeks of packaging? Should I just toss it?
