Myth: I should be able to safely can any of the canned foods I buy at the grocery store.
Just because you buy something in a jar that was canned, does NOT mean that it is safe for you to try that at home. Commercial canning equipment often hits higher temperatures, operate in sterile environment, include lab testing of representative homogenized batch samples for pathogens, and other safeguards that do not exist in a home kitchen or with home equipment.
