I took my kiddo to a strawberry patch a couple weeks ago and we came home with two GALLONS of strawberries. I love fruit but that's a bit more than my family can consume before they go bad. So my solution, directly from the attic (well, my mom's attic) was a dehydrator!
I consider dehydrating kind-of an old-fashioned craft. These days, you can find dehydrated fruit and meat (jerky) at every grocery store and gas station. But dehydrating yourself is a great way to ensure natural ingredients. It is also a good method for using up fruits (and veggies and meats) before they go bad. You can add flavoring if you want, but its totally up to you. Dehydrated foods can be kept without refrigeration for long periods of time. They can also be re-hydrated for uses in recipes and food prep. My favorite is just to eat them as a healthy snack!
In our case, the dehydrator had literally been in the box and last used 15 years ago. We scrubbed it off and read the instruction pamplet and had our dehydrating in progress with less than 20 minutes of food prep time. Then you just plug in the machine for 12-36 hours! The berries turned out yummy and we decided to experiment with some other fruits.
This is what a dehydrator looks like - ours has 7 trays and is really simple, with a heating element at the bottom that puts off very little heat.
So my simple example: Fresh fruit -- so far we've tried bananas, pineapple, strawberries, and apples:
