2. Drying

Drying is considered to be the easiest and least labour-intensive way to preserve food. Since mold, bacteria, and mildew thrive in a moist environment, drying is effective for food storage because it removes all water and can be stored safely for a long period of time. You can buy a food dehydrator or use a low-temperature oven, although the latter can take many, many hours to accomplish the task.

Dried food, especially fruit, can be eaten as is, or you can rehydrate it by soaking in water for several hours. You can also make delicious snacks such as fruit leather and beef jerky. (Here's an excellent recipe for jerky that I like to make.)
