I agree compeltely with Glauber Rocha; @Shirley, although you asked about storing in the refrigerator, it is worth noting also that caramelized onions store very well in the freezer, up to six months. â Bruce Goldstein Dec 12 '11 at 16:01.
Cut onion can be stored 7-10 days in a sealed container in the refrigerator. I've not experimented specifically with glass or plastic, but I can understand how glass would be better. I'll have to give that a try. Sharp knives are key, that was a spot on tip!
