I received an ENORMOUS jar of sliced lemons packed in vinegar of unknown type. It is looking pretty in my kitchen but I don't want to open until I have some idea of what to do to open it until I have some idea of what to do with the lemon slices. I think this was a fairly common gift item in kitchen stores - does anyone have any experience? Can I use the lemons in food or is this destined to look pretty in my crowded kitchen? Thanks in advance.
