For Christmas, we received a large box of Williams-Sonoma's ricotta croissants. They're frozen -- you just thaw overnight and bake. I just realized we have half the box left. But the directions say they "will keep frozen for up to 3 months." I'm not quite sure what this means -- I would assume the quality might have gone downhill, but that there is no actual danger of getting sick, since they've been in the freezer this whole time. But I wanted to run it by some others, first. Thoughts?
