Adventures in Dehydrating, Part 2

So, you’ve found your dream dehydrator and you are ready to get started. The dehydrating process is not especially complicated: Food is dehydrated by subjecting it to low heat and a steady airflow, evaporating enough moisture to inhibit the growth of bacteria, yeast, and mold—things that spoil precious food. You want food to be as dry as possible before storing it. Along with your dehydrator’s manual, the Internet has many reliable sources of dehydrating instructions (see resources below), so I won’t reinvent that wheel, but I will share some things I encountered during my first year of dehydrating.

Prepping Food
Ideally, all dehydrated food should end up at the same level of dryness, so chopping, cutting, or slicing food into uniform pieces makes sense, right? Imagine starting one thick and one thin burger on the grill at the same time: You know that the thin one will cook more quickly. Some obliging vegetables like corn and peas come uniformly sized. To cut up larger produce, many people use a mandolin. Since I typically shred my knuckles on a plain old cheese grater, a mandolin is probably not in my future. Seriously, mandolins are out for blood. An egg slicer works great for strawberries and mushrooms. Depending on the size and shape of the food, I either use sharp knives or my trusty Oster Kitchen Center.

Dehydrating Times

As shown in the chart below, dehydrating times vary, with juicier foods like peaches and pears taking longer to dry than, say, apples.

Some people ignore the recommended times altogether, leaving the dehydrator on for 24 hours no matter the food. Can you over dry food? Most sources say no. So how do you tell if the food is “dry enough”? The USDA says that dried vegetables should be hard and brittle, to the point that some will shatter when hit with a hammer. Before you pull out the ol’ ballpeen, take out a few pieces of food and let them cool before testing—warm food tends to seem moister and more pliable.

You may end up varying dehydrating times, but do not mess with the recommended temperatures. For example, if the initial temperature is too high, the food surface might dry, making it hard for moisture to escape. Instead of upping the temperature to speed up drying time, cut food into smaller or fewer pieces.

Adventures in Dehydrating, Part 1

Throughout my years of researching and studying food preservation methods—canning, freezing, pickling—I was always lured by dehydrating. I envisioned my pantry shelves filled with jars of efficient, shrunken vegetables just waiting to be resurrected. And seeing photos of stacked trays, all loaded with Martha-Stewart-neat rows of bright fruits and vegetables? Absolutely. And in reality? That IS the reality!

In the first of this two-part blog, I will share my experience in buying a dehydrator; in part two, I will talk about the dehydrating process.

The most important features to me were ease of use, size of the unit, and noise. Both price and capacity were somewhat secondary. Your prioritization of these characteristics may be completely different.

I was convinced from the start that I would buy a top-of-the-line Excalibur dehydrator. I usually buy the best tool I can afford because I don’t want a substandard tool to interfere with my ability to do a job. The more I researched, the more I realized that I probably did not need such a large dehydrator, and it turns out I was right.

This six-tray Cosori dehydrator meets my needs perfectly.

Before I bought one, I spent many hours researching dehydrators. I mostly read articles about what to look for in a dehydrator. I recommend you do the same to figure out what you want/prefer. For example, dehydrators come in different shapes and configurations: Basically, they are either rectangular and look kind of like a microwave with multiple shelves, or they are comprised of a stack of round trays. Most of the round ones have plastic trays but I wanted sturdy stainless-steel trays. Plus, I just didn’t like the round shape—hardly a scientific justification.

MEET DANIELLE BARSE, MASTER FOOD PRESERVER VOLUNTEER

How long have you been preserving food?

Since 1997. I started with my father’s green tomato pickle recipe and venison. My aunt and I spent a weekend canning and divided up the food. My next adventure involved canning squash, which I learned shortly thereafter was a bad thing! I did not do it correctly, and it spoiled in my pantry. The jars leaked the fermented, rotting squash, and it smelled very bad.

What are your favorite preservation methods?

I like dehydrating foods because it is easy; it saves space; and it’s versatile. I also enjoy pressure canning—I find I preserve many more low acid than high acid foods, the latter of which can be processed in a water bath canner. Plus, I can a lot of meat, which requires pressure canning.

Jar of canned meat. — Danielle likes to make a mixed ground meat as a hunting camp staple. It’s versatile and she fries it up like hash, adds to breakfast burritos, includes with Spanish rice in stuffed peppers and more.

What are some of your favorite foods to preserve and why?

I like to dehydrate apple slices until they are crunchy. I eat them like potato chips or crumble them into cereal, yogurt, or quick breads. I also like to pressure can meats for use as a quick meal solution on busy nights. I can chicken, pork, venison, beef, and turkey, which we use in tacos, casseroles, sandwiches, soups, stews, and stir fry. I like to make and can shepherd’s pie that my family need only heat up before eating. I also make and pressure can many, many different types of soup.
