I think this falls under the post the other day about things in your cupboard that haven't been used in awhile . . . but . . . I have some balsamic glaze (the Modena, Italy kind, I think the brand is Gia Russa) that has been in my cupboard for about six years. It has been opened and I have used it three or four times and then I forget about it. It didn't say to refrigerate on the label, so I didn't. Do you think it is still safe to use? The last time I used it was last year. For tomorrow evening I am making lamb chops and wanted to do a cherry balsamic sauce. Should I chuck it and by a new bottle or takes my chances???
