It''s really pretty simple. If you buy a pressure cooker, just follow the directions that come with it. Beef can be processed raw, pressure cooked in sterile jars at 11lbs pressure for 90 minutes. Its ready to eat once removed from the can. The "test" for a good seal and food safty is to tap on the can lid with a metal spoon, etc., if it sounds like "tink" it''s good, if it sounds like "thunk" it''s not good. From my experience the cost of a quart of beef is about $5, I seriously doubt you can purchase pre-canned meet at that price. Sometimes you can find a pressure cooker at a good will store for little money, the sealing gasket (rubber) will most likely need replaced and carried by most well stocked groc. stores or household department stores such as K-Mart. Try it, you''ll be impressed with the results. Try searching the web for "canning" there are some websites on it.
