The Lost Arts of Food Preservation Shelf

Everyone likes their food, naturally. What people don't like is spoiled food. If you're offline and your refrigeration fails, that can be a crisis if all of your food is only preserved via cold. You can lose a lot of food if you have a power failure or equipment failure. Naturally, we got here not because we had frostless freezers since the bronze age, but we had knowledge of how to preserve our food for the future using salt, smoke, and other techniques.

Food preservation really opened up when we discovered pasteurization and an understanding of basic microbiology--that is, knowing what kinds of bacteria or molds can spoil food. Canning will require you to get some new kitchen tools for safety, because  handling jars of delicious liquid-sugared napalm demand it.
