One thing we have tried to do in our food storage is to stock items that store well and are versatile. A good example is spam. Hormel says that it will last indefinitely unless the cans are punctured or damaged. They do state that after the best use date there may be changes in taste and loss of nutrition. In my experience, this takes many years before a change in taste is noticeable.
Now I know that not everybody likes spam, personally I do. However, span can be used in a large variety of ways. It can be eaten cold right out of the can or cooked. You can use it in almost anything from stews to adding it to macaroni and cheese. In Korea, they even use it for a kind of sushi. It became popular over there after the Second World War.
A quick search on the internet will reveal a large number of recipes for different ways to cook it. I even found a recipe for apple and span turnovers. Spam is just an example of what I am talking about; there are other products that can be used in multiple ways. Canned tuna and chicken are other good examples.
In the future, we will post some off our favorite recipes using either home or commercial canned foods. Writing about this has made me hungry and I am going to go and make myself a spam sandwich.
