I hate throwing the Azera tins into the recycling, but have never found a good use for more than a few of them. But I'm making jams and jelly right now, and wondered whether I could use the Azera tins as an alternative to glass jars. Does anyone know whether this would be OK? I cannot find anything on the internet to say yes or no, and so many searches for "can" just seem to assume you mean glass.
