How do I store it?
What do those numbers on it mean?
How long will it last sealed up? Opened?
Where do I store it?
What's with the "Use By", "Best Before", and "Expiration Date"?
What do I do if I suspect insects near it?
What about molds?
I went searching for links to do a permanent "sticky" post here in the kitchen, where it will cover both normal, day-to-day food storage, and helpful guidelines for long-term storage. If you have links to these things, feel free to post them, too.
This first is VERY helpful information compiled and (I believe) edited by Alan T. Hagan, who has been a member here since 12/13/05, though he visits and posts infrequently. He's done an excellent job, and I would suggest you read it all...
