Hi. I haved a tubg of piping gel that I last used in May 2013. I was told that it didn't really have a use by date or go off and can't see one on the tub. Just thought I had better check with you guys here to see if anyone knew that it DEFINITELY doesn't go off before I go using it on another cake. If it DOES go off, does anyone know how long it is recommended to keep it from opening the tub?
Thanks in advance.
