Ask a Mormon family to see their pantry and you might get a tour of the kitchen, but ask to see their "year's supply" and given the house's floor plan, you'll probably end up in the basement.
A year's supply is an LDS tradition, heavily encouraged by church leaders, in which individuals and families carefully plan, can, jar, and store basic items (water, flour, rice, salt) in ratios per person in the house and per month of expected storage.
Church members say a year's supply is never something purchased at once or backed into the garage with a truck. The collection (of what could easily be mistaken for a quick fix for 2012 or total wipeout) is a stash of long term storage with a rotating "three month's" supply of more perishable food items in case of community disaster, a sanitation issue — hell, even a crappy economy.
It's all about preparedness, church documents, and food preparation pamphlets, and it's often hard to do (especially in the desert and in houses without pantries — or basements). But individuals and families have adapted and thank modern-day solutions (read: The Container Store) for tubs easily disguised as hallway benches and false shelves that rotate to reveal hand-jarred preserves and tightly packed grains.
