Yes, there is a distinct process involved, and once learned, it is an immediately useful skillset, as you can start putting up quality food anytime you want. There are even recipes for making home made Spam.

I've canned all sorts of meat products, from ground beef, chicken, salmon, moose chunks, sausage, hot dogs, corned beef hash, turkey, shrimp, chili, bacon, and even meatloaf (an accidental discovery).

As with anything worth doing, it takes an investment in time, effort, and money. The return on investment is high, and if you are reasonably diligent about it, you will save enough from canning your own than what you'd pay for inferior commercial product from the store to cover the investment in no time.

Wouldn't you rather eat something you made from scratch, knowing what is in it, instead of the mystery meat in a can?
