Introduction to Dehydrating

Today it’s my pleasure to introduce you to my very special guest, Darcy Geho. Darcy is the owner of PreservingMySanity.com, a lifestyle blog focused on natural living, healthy cooking, and food preservation. Darcy and her husband live in Minnesota with their dogs and cat, where they all enjoy the summer more than the winter. Having the extra refrigerator (aka the porch) does come in handy, though!

I asked Darcy if she would discuss dehydrating with us today because many of you have requested information and I don’t have much experience with it. As you’ll see, Darcy LOVES dehydrating, so she’s the perfect person to educate all of us. Take it away, Darcy!

Introduction

If you are like me, you love your garden and all of its bounty, but by the time it’s peak harvest season it can get a bit overwhelming. I’m a canner at heart and love water bath canning and pressure canning like so many of you, but I’ve somewhat recently found a new love for dehydrating.

I live in Minnesota and our growing season is short though productive, which means a LOT of work has to get squeezed into a few months’ time. Pair that with the fact that my 1880 Victorian home doesn’t have central air conditioning, and sometimes the idea of running the stove burners for hours at a time just isn’t very appealing.

Dehydrating is Great for Several Reasons

First: It’s easy! For the most part, all you have to do is wash and chop your vegetables, fruits, or herbs and put them in the dehydrator. You do need to blanch some of the vegetables before dehydrating. A general rule of thumb is if you would normally cook the food before eating it, you should consider blanching it before dehydrating it. This isn’t a safety concern, but can affect the texture and desirability of the final product.

Second: It saves SO much space! I put 32 cups of shredded zucchini in my dehydrator and when it was done, it fit into a 1-gallon freezer bag. This is just one example! Check out the pics below for another one!

Third: It is energy-efficient! The book that came with my Excalibur 9-Tray Dehydrator says it costs 3 to 6 cents per HOUR to run it. That’s it! It also doesn’t heat up the house, which is crucial for me in the summer months.

Fourth: It saves money! Not only can you preserve the foods harvested from your garden quickly and easily, but you can also keep your dehydrator in mind as you are shopping at the grocery store. Are they selling a large bag of overripe bananas for a couple of bucks? They make great banana chips!

Fifth: It is healthy! Dehydrating allows you to preserve your garden harvest quickly. When I dehydrate my greens and herbs from the garden, I literally pick them, wash them off, chop them, and put them in the dehydrator. As we all know, nutrients fade from produce over time, and you can’t get it preserved much quicker than that.

The Equipment

Until this year, my dehydrator was an old round Ronco brand without a fan or temperature dial, and to ensure even dehydration you had to rotate the trays every few hours. We mainly used it for venison jerky and banana chips.

Though our old dehydrator worked ok, it was actually about to break completely in half. Also, I was interested in expanding my dehydrating experience beyond jerky and banana chips. This summer, I found a really great flash sale and replaced my old dehydrator with an Excalibur 9-Tray Dehydrator. Happy Birthday to me! After that, I went a little wild and dehydrated all kinds of things.

Important Dehydrator Features

If you don’t have a dehydrator and will be purchasing one, I recommend selecting one with a temperature dial and a fan. A timer is also a nice feature, but not crucial. If an Excalibur isn’t in your budget to start out with, that’s ok! There are less expensive options that work well too, like this Nesco Gardenmaster Food Dehydrator.

The temperature dial is important because different foods should be dehydrated at different temperatures. For example:

  • Herbs – 115 degrees (Fahrenheit)
  • Greens & Vegetables – 125 degrees
  • Fruits – 135 degrees
  • Jerky – 165 degrees

After using my new Excalibur, I was so amazed at the bright color retained in my greens and herbs compared to products dried in my old dehydrator. Once you look at the temperature differences required for each category, you can see why that would be the case. In my old one, I was dehydrating herbs and jerky at essentially the same temperature!

The fan is also an important feature, because it helps to retain even drying time throughout your trays.  Again, with my old dehydrator, I had to always rotate the trays to try to get things done evenly.  The fan allows you to just set your trays in place with your product on them, set a timer, and basically forget it and let it do its thing.

How a Food Processor is Helpful

Another piece of equipment you may want to consider purchasing (if you don’t already have one) is a food processor. This is an essential tool if you are planning to make powders with your dehydrated things – think beet powder, vegetable soup base, chicken bouillon, etc.

Things to Dehydrate

So, in terms of what you can dehydrate, the options are really quite endless.  Fruits, vegetables, greens, herbs, jerky, fruit leather, yogurt, sourdough starter, the list goes on!

Fruit

  • Banana chips are by far my favorite thing to dehydrate. They are SO much better than the ones you buy in the store. I also like to chop them up and use them in baking, specifically banana nut bagels.
  • Lemon and orange slices are great for water and tea, but you can also use them in marinades and sauces.
  • Tomatoes are a bit tricky to dehydrate because they have SO much moisture in them. It is possible, though! A lot of food preservationists actually take their tomato peelings and seeds from their salsa and sauce making and dehydrate them! Once dehydrated, you can grind them in your food processor, and you have some killer tomato powder to mix into your cooking. Another idea for tomatoes is to marinate them in oil and seasonings and then dehydrate them. Due to the oil, they aren’t shelf-stable and have to be frozen after dehydrating, but we love them on salads.

Herbs & Greens

  • Arugula & Kale – I love dehydrating greens. We use them throughout the winter in soup and in other dishes. We don’t grind ours into powder, we just crush it as we use it. But, you could use your food processor to make green powder to incorporate into various things. Swiss chard would also work well, though we usually end up eating all of ours fresh before there is a surplus left to dehydrate.
  • Herbs – We usually grow a variety of herbs in our garden. I used to air dry them, and this year was the first time I officially dehydrated them. What a difference! The color remained beautifully green, and their flavor is amazing.

Vegetables

  • Mushrooms – Good mushrooms are hard to find in my small town grocery store, so I always have sliced and dehydrated mushrooms on hand.  I actually store mine in the freezer, because I am never fully confident that they are fully dehydrated. They are kind of weird like tomatoes. But, I can dehydrate an entire machine full of mushroom slices and fit them into a 1-gallon bag for freezer storage. That’s a pretty amazing space-saver if you ask me!
  • Shredded zucchini – I dehydrated shredded zucchini for the first time this summer too. I’ve read that you can rehydrate it and use it in baked goods just like regular shredded zucchini. I am excited about how much space this saved in the freezer and am looking forward to trying it in some bread.
  • Green beans – I dehydrated green beans for my mom this summer so she could use them in soups. I actually did not blanch them first, and apparently should have. Even once we rehydrate them before using, the texture is kind of weird. I would try this again though and blanch first.
  • Peppers – I dehydrated diced green bell peppers this year to be used in chili. I also often dehydrate various hot peppers to be ground into pepper flakes and chili powder.  My husband and I smoke large batches of serrano peppers each year and finish them off in the dehydrator. They are our favorite!
  • Beet Powder – I don’t really care for beets, but due to their health benefits, I wanted to sneak them into more things. I dehydrated beet slices and used my food processor to make beet powder.
  • Vegetable Powder – You can use the same process I used in making my beet powder for really any variety of vegetables. Mixed vegetables, vegetable scraps even! Anything you would throw into a vegetable soup, you can dehydrate it and then use your food processor to turn it into powder. It’s a really easy way to “sneak” more vegetables into your cooking.

Other

Here are some other ideas for some less obvious things that can be dehydrated. To do these things, you need to purchase some sheets to line the trays of your dehydrator. Some examples of these would be the Excalibur Silicone Dehydrator Sheets and Nesco Fruit Roll Sheets for Dehydrators.

  • Fruit Leather
  • Yogurt
  • Sourdough Starter
  • Bouillon / soup base

Storing your Dehydrated Goods

For long-term storage of your dehydrated goods, you want to be sure you store them in an airtight container.  Mason jars work well, but I save glass jars from commercial products so I don’t “waste” my canning jars on dehydrated goods. Either way is fine, as long as it’s airtight. Keep in mind that freezer/storage bags aren’t airtight, and neither are most plastic storage containers.

Though I keep most of my dehydrated goods in airtight jars, I do store a few things in the freezer. Sliced mushrooms, shredded zucchini, and those marinated tomatoes I mentioned all go in my freezer. This is a personal preference for me – the only thing out of these that really isn’t shelf-stable is the marinated tomatoes.

A few other steps you can take for storing your goods:

  • Place silica packets into your jars with your finished products. Their purpose is to absorb any potential additional moisture that may be in the jar.

These extra steps aren’t entirely necessary, so you can do what you are most comfortable with for your family. The most important things are to ensure your product is fully dehydrated and to store it in an airtight container. For the purpose of this post though, I wanted to give you all of the options for storage!

Reconstituting your Dehydrated Goods

When it comes time to use your dehydrated items, many of the products will be better to eat if you reconstitute them in water first. For example, if you are making soup and drop pieces of dehydrated kale into it, the kale won’t really cook and it won’t really hydrate.  But, soak it in some water for at least 30 minutes before putting it into your soup, and the end result is completely different. Dropping it into boiling hot soup just isn’t the same as reconstituting it slowly in regular water.

Mushrooms must also be reconstituted before using, and it gives you amazing mushroom broth to use, too! Shredded zucchini is another example. Before using it in baked goods, it needs to be reconstituted first to get that moisture back into it.

Not everything needs to be reconstituted, of course. The arugula and herbs can be easily crushed into your cooking. As you get into it and dehydrate more things, you will learn more about what needs to be reconstituted before use and what doesn’t.

Summary

Thanks for letting me tell you all about dehydrating!  If you would like more information, a couple of my favorite resources are Excalibur and The Purposeful Pantry.

I’m also happy to answer any questions you may run into on your dehydrating journey. You can find me over at PreservingMySanity.com.

Thanks for the great post. I am off grid so running a dehydrator for hours is not something I can do often (Sunny summer days perhaps) but you did get me thinking. Do many things take mare than 4-6 hours?

Since I wasn’t sure on the answer to your question, I went right to Darcy and asked her. This is what she said: “I have an Excalibur 9-tray dehydrator and it has a 7″ fan and uses 600 watts. A dehydrator should have at least 500 watts to do the job properly. Most fruit is going to take anywhere from 8 to 24 hours to dry, depending on the fruit. Vegetables are a bit faster, but most are going to take between 6-12 hours. Greens and herbs are the quickest and can usually be done in 4-6 hours. So no, I would say most things cannot be dried in 4-6 hours. The low temperature over a long amount of time is what enables the quality of the food to be preserved. If you tried to do it hotter for less time, you would just cook and/or burn the food – not really dehydrate it. And, if you don’t dehydrate things fully, you risk bacteria growth and spoilage.” I hope that answers your question. Thanks for reading!

I’ve always thought I’d like to own a dehydrator but I’ve never bought one. I do dry my herbs though but I just dry them on the counter in the kitchen. Love the reconstituting tip! I did not know that.
