We've got a lot of summer still to go, but at this time of year, my mind trains on fall. It's my favorite season for a variety of reasons, foremost of which is all the delicious food. Autumn is when the slow cooker gets its dedicated spot on our kitchen counter and when warm, hearty meals replace simple salads at dinnertime. (See also: 8 Good Reasons to Learn Canning Now)
It also happens to be when our CSA share is at its peak; our farmer friends send us home each Saturday with literally barrels of tomatoes, cucumbers, squash, apples, and all sorts of other natural goodies. I consider myself quite a voracious home chef and even I can't seem to find use for all the diverse fruits and vegetables that come my way. And I don't want them to go to waste.
I'm on a personal quest this year to learn more about the art of food preservation. In my search, I've come across some useful texts on the subject, as well as some budget-friendly tools of the trade. Here is a brief description of the most popular preserving methods, as well as my favorite books about each (and all).
Canning is a method for preserving food in which items are heat treated and then sealed in containers (glass jars are a popular example). Most anything can be canned, including jams, sauces, and other creations — as well as whole foods to be enjoyed at later dates. Canning gives food a shelf life of anywhere from one to five years, sometimes more.
Freezing foods is an easy solution if there's enough the space for storage. Foods are prepared, then placed in airtight containers and — that's right — frozen. The cool, dry environment of a freezer helps eliminate the bacteria that would ultimately lead to spoilage. This method typically gives a shelf life of anywhere from three months to a year.

Pickling preserves food in brine (in other words, salt water), creating an acidic environment which kills bacteria and produces a delicious sour taste. Foods are placed in the salt solution for a specified amount of time, after which they can be stored in airtight containers — usually refrigerated — for several more weeks before going bad.

Dehydrating can be performed by cracking the oven door a bit and baking at low temperatures. More recently, cooks have used dedicated dehydrating machines. It's actually one of the oldest and easiest methods of food preservation and works by removing moisture from foods. Since bacteria and other spoilers need wet environments to thrive, it preserves well — when items are properly stored — for up to a year. (See also: 9 Money Saving Reasons to Buy a Food Dehydrator)
There are also several good books with a little of everything.
Once you've made your way through the reading, it's time to get started. In my next post in this series, I'll hunt down deals for the basic items you'll need as you embark on your own adventure to a fridge, freezer, and pantry full of healthy, self-preserved foods.

My favorite is freezing foods to preserve them, especially fruits like bananas and strawberries since they get back SO quickly! These make great soothies later and it much more frugal than throwing them away.
