A few months ago me and my friends was talking about how we always have this type of food in stock come hell or high water growing up. For example somebody will still have a can of corn or something readily available if nothing else. For me growing up my mom always kept white rice in stock and powdered milk, canned meats, canned fruit, sugar, condensed milk, tea, coffee and Kool-Aid...lots and lots and lots, of Kool-Aid.
So when the zombie apocalypse, alien invasion, or the rise of the machines happen, what food is guaranteed to be in your kitchen.
