Raisins from Grapes in a Food Dryer

Posted By: Daniel Gasteiger  //  Category: dry fruit
washing grapes for the food dryerUnless you grew the grapes, you can’t be sure what’s on them. Come to think of it, even if you grew the grapes, you probably didn’t keep bugs and birds from er… making deposits. Wash them thoroughly before you commit them to the food dryer.

Have you used your food dryer to make raisins out of grapes? Try it! Store-bought raisins are tasty and all that, but homemade raisins put the store-bought ones to shame. I expect never to buy commercially-packaged raisins again now that I’ve made my own. Whenever I anticipate wanting raising for cooking, baking, or salads, I load up my dehydrator and let it do its magic.

Making Your Own Raisins

I use only seedless grapes when I make raisins. I can’t imagine trying to remove seeds from grapes, and there’s no way I want to bite into a raisin that has a woody center.

puncturing grapes for the dehydratorYou can skip this step, but it’s not as time-consuming as it might seem. I puncture each grape in two places using the tip of a paring knife. Stabbing the fruits when you dry blueberries is almost imperative, and I’ve added the step to my grape preparations to promote more even and quicker drying.

Which reminds me of something I despise about commercial raisins: many of them have dehydrated stem stubs still attached; I pick through commercial raisins and tear off those stem remnants before I incorporate commercial raisins in my dishes. Happily, when I make my own raisins, I can pick through the grapes and make sure none have stems attached before the grapes go into the dehydrator.

One other thought: grapes skins are impressive water barriers. I stab each grape in at least 2 places to provide places for water to escape from the grapes in the dehydrator. While you don’t have to stab your grapes, I’m convinced they dry a bit faster when you do. In any case, at 135 degrees Fahrenheit, it can take 10, 20, even 30 hours to dehydrate grapes into raisins. Check on them after 10 hours, and, perhaps, every two hours after that until they’re shriveled, pliable, and chewy. Raisins from my food dryer are always plumper than commercial raisins, and they taste much, much better.

grapes on the food dryer drying trayAs I puncture the grapes I deposit them on my dehydrator trays. By the time I’m done, this tray will be quite full. It’s OK if the grapes touch each other, but don’t pack them in so tightly that they wouldn’t move if you tilted the trays.
raisins coming out of the dehydratorThese raisins emerged from my food dryer after about 36 hours of drying! A few raisins were still plumper and juicier than is ideal for long-term storage, but these went into a pie within a few hours of leaving the dehydrator. Monitor your drying grapes. If you leave them too long, they become very hard and even brittle; you might actually prefer commercial raisins over ones that dry too long at home.

How to Make Yogurt with a Food Dryer

Posted By: Daniel Gasteiger  //  Category: food dehydrator

Since writing Yes, You Can! And Freeze and Dry It, Too, I’ve had several people ask,”How do you make yogurt in a food dryer?” Happily, the food dryer part of the answer is really simple: If your dehydrator has a temperature control, you can use it as an incubator in which to grow cultured yogurt. With that out of the way, the question becomes, “How do you make yogurt?” and the answer can be very simple or very complicated.

The method I explain here is very simple and it makes very respectable yogurt. However, Google “how to make yogurt” and you’ll find dozens of articles and videos each having its own spin. Explore, find the method you like best, and still you’ll be able to use your dehydrator as a yogurt incubator.

What You’ll Need to Make Simple Yogurt in a Dehydrator

Yogurt Containers for a Dehydrator

The yogurt-making method I explain in this blog post makes just over a quart of yogurt culture. You pour the culture into a container or containers and incubate it for about four hours. You can use a single quart-sized container, or several smaller ones: four 1-cup bowls, six 6oz used yogurt containers—but whatever you use, you need a lid for each container.

More importantly, because you’re incubating the culture in your food dryer, the covered container or containers must fit in it. For a cabinet-style dehydrator, you can remove several trays to make room for a tall container. However, for a stackable-tray dehydrator, you’ll need to find shallow containers that can fit between two trays; that’s a tall order.

Let’s keep it simple. To make yogurt, start with the following items:

  • 1 quart of milk (skim, 1 percent, 2 percent, or whole… even raw is fine)
  • ¼ cup of plain yogurt – use only yogurt that clearly identifies itself as containing live culture—or probiotic.
  • 2 quart or larger sauce pot
  • Whisk
  • Spoon
  • Ladle
  • A cooking thermometer
  • Container(s) with lid(s)—see the box for thoughts about containers

How to Make Yogurt in a Dehydrator

Start by sterilizing the containers in which you’ll incubate your yogurt culture. At the same time, bring the milk to boil. Stir the milk occasionally while it heats, and watch when it boils so you can keep it from boiling over; it will generate foam and try to escape from the cook pot.

Let the milk cool until it reaches 115 degrees Fahrenheit. Then, add the yogurt to the warm milk and whisk it thoroughly to ensure that the yogurt dissolves through the entire volume of milk.

Fill the containers with the milk and yogurt mixture, cover the containers, and set them into the dehydrator. Set the dehydrator at 115 degrees Fahrenheit.

Check the yogurt after four hours. It may have become a very thick liquid, or it may have set up harder than that (encourage a harder set by boiling the milk longer before cooling it). In either case, it’s ready (there may be whey on the surface—a nearly clear liquid). Yogurt becomes tangier as it incubates, and if you let it go much beyond eight hours, it can become far tangier than most people prefer.

When the yogurt is thick or firm, move the containers to the refrigerator and let them sit for several hours to cool. Save ¼ cup of your homemade yogurt to use when you make your next batch; you should never again need store-bought yogurt.

Tomato Skins in a Food Dryer

Posted By: Daniel Gasteiger  //  Category: dry fruit, food dryer, food drying
saved tomato skins for the food dryerThe skins from a peck of tomatoes covered three trays in my American Harvest food dryer, but I overlapped pieces liberally.

Here’s a way to use a food dryer that raises eyebrows wherever I mention it: Dry tomato skins. I got the idea in a Facebook group about home preserving; one of the participants said that when she cans tomatoes she saves the skins and dehydrates them to use later in soups and sauces. I was canning a lot of tomatoes, so I decided to try it.

Unusual Food Drying

I saved skins from about a quarter of a bushel of tomatoes as I prepared them for canning, diced, in pint jars. When I set the skins on dehydrator trays, I intended not to overlap them, but given how thin they are, I decided they’d be fine even if some stuck together.

I dried the skins at 130F degrees overnight and by afternoon the next day (I didn’t bother to check until then), the skins were dry and brittle.

What to do with dry, brittle tomato skins? I scraped them off the food dryer’s trays into the pitcher of my blender, and pressed them down so they cracked and settled around the blender’s blade. Then I put the lid on the blender and ran it until the tomato skins were powder. Finally, I dumped the powder into a storage container and snapped on the lid.

Using Powdered Tomato Skins

powdered tomato skins from a food dryerThe skins from a half peck of tomatoes dried and pureed into powder only partially fill a small storage container. Will you use tomato powder as seasoning or as soup base?

The skins from a peck of tomatoes aren’t going to stretch far, but if you can a bushel or two of fruit, you’ll build up a compelling store of tomato powder. You might discover that tomato powder makes a great seasoning to set out with your salt and pepper shakers. For more conventional applications, try these proportions.

To make…

…tomato paste, mix one measure of tomato powder with one measure of water.

…tomato sauce, mix one measure of tomato powder with three measures of water.

…tomato juice, mix on measure of tomato powder with one measure of water, and one measure of cream.

Your Food Dryer and Beyond

Posted By: Daniel Gasteiger  //  Category: dry fruit, dry vegetables, food dryer, food drying
My book, Yes, You Can!

I’ve neglected Food Dryer Home because I was writing a book about preserving food! It includes a detailed chapter about dehydrating produce with many step-by-step sequences and photos. Click here to buy your copy from

It’s no secret that I’ve neglected my blog about dehydrating food. This is, in part, because I was writing a book.

Canning, Freezing, Drying, Fermenting, Sugaring, & Cold Storage

My book, Yes, You Can! And Freeze and Dry It, Too, from Cool Springs Press, came out in March. It started as an idea for a book about canning produce, but evolved quickly into a survey of most home food-preserving methods.

I wanted Yes, You Can to feel as though you had asked me about preserving produce, and then indulged me by joining me in my kitchen to do a whole bunch of projects. Sure: there’s a linear narrative… we need to preserve some produce, after all. But along the way, there are dozens of digressions: tips, history, stories from my kitchen, and other tidbits to ease the learning process.

Yes, You Can! isn’t one of those dry, gray, “here’s how it’s done” books. It’s loaded with photos that illustrate step-by-step how to complete preserving projects and how to use the foods you’ve preserved. The chapter about dehydrating foods includes instructions for prepping produce, blanching vegetables, and drying vegetables and fruits. It suggests some great snacks to prepare in your dehydrator, and shows how to refill your spice jars from your own herb garden. It even explains how to prepare one of my favorite breakfasts starting with dehydrated shredded potatoes.

I hope you’ll click through to Amazon and see what others have said about my book. I had a great time creating it, and I think you’ll enjoy reading it and working from it.

Alternative Uses for a Food Dryer

Posted By: Daniel Gasteiger  //  Category: food dehydrator, food dryer, solar dryer

I came across an article that suggests how you might put a food dryer to use for tasks other than drying food. The terms of use for the article require that I not change a word in it. However, I want to point out that the author clearly has an agenda to get you thinking there’s something special about a particular brand of food dryer. Never mind that. The suggestions for how to use a food dryer are both creative and useful.

Please enjoy this article about practical uses for a food dehydrator:

Actually… when I published the article, Google immediately trashed the ranking of my Food Dryer blog. This has become a recurring problem for articles I’ve republished from article services. So… I’ve taken down the original article and have paraphrased it below. Because of this recurring problem, I will no longer publish the full text of previously-published articles in this blog.

I hope you’ll still visit; I’ll continue to post information about drying fruits, vegetables, and meats, and about the equipment available to help with these projects.

My Spin on 11 Ways to use a Food Dryer

An eZine articles piece describing 11 odd but practical uses for a food dryer offers… well, eleven suggestions for how you might use a food dryer. Please visit the original article for details. Here are the suggested uses:

1. DRY PASTA: When you make your own noodles, your dehydrator can dry them quickly.

2. MAKE INSTANT PASTA: Have you ever eaten Ramen noodles? They’re actually dehydrated cooked noodles. This explains why they cook so rapidly. If you dehydrate your own cooked noodles, they’ll rehydrate quickly in boiling hot water.

3. REFRESH CRACKERS: When crackers get soft or a bit stale, revive them with a stint in your food dryer.

4. HUMIDIFY: A food dryer pulls moisture from food, and blows it into the air. If your house is dry, you can add moisture to the air by dehydrating several plates of water.

5. MASK ODORS: Do you want to get that fishy or deep-frying odor out of your house? Run a few slices of orange, lime, lemon, or grapefruit in the dehydrator for several hours.

6. AROMATHERAPY: You can use your food dryer as an aroma therapy diffuser: use your favorite scented oils and herbs, place them in a small open container, and set it on a rack in the dehydrator for the duration of your aromatherapy treatment.

7. MAKE BREAD CRUMBS: It’s easier to make bread crumbs from old bread if you dry the bread thoroughly before grating it or processing it in a food processor. So, first leave the bread in your food dryer until it gets particularly arid..

8. MAKE POTPOURRI: The sky may be the limit on what you include in your own potpourri. Dry citrus peels, herbs, flower petals, and grasses, then mix them in your own blends.

9. MAKE FIRE STARTERS: Apparently, dried citrus peels contain enough oil that they burn very nicely. When you peel an orange, dry the peels thoroughly and add the finished product to your emergency survival kit.

10. SNACKS FOR YOUR PETS: Buy parts of animals that you’d never eat, such as ears, snouts, and feet. Process them in your food dryer, and they make terrific chew-treats for your dogs.

11. VEGETABLE AND FRUIT POWDER SEASONING: An Indian dish I particularly enjoy calls for mango powder, which isn’t available in stores where I live. I can buy whole mangos, slice them up, and dry them in my food dryer. Then I process them to powder in my food processor and I have mango powder. You can do this with any fruit or vegetable to create great seasonings you can’t buy in a grocery store’s spice section.

Dehydrate Tomatoes in a Food Dryer

Posted By: Daniel Gasteiger  //  Category: Uncategorized
Tomatoes ripe for the Food Dryer

It’s great to have a food dryer during peak produce season… and better still to have one as the season draws to a close. I had canned many gallons of tomato sauce, salsa, and diced and halved tomatoes, and found myself with several dozen small tomatoes that weren’t destined for a cook pot. Then a friend on Twitter made a comment about drying tomatoes.

If you haven’t dried tomatoes yet, please try it as soon as you can. I dried two dozen tomatoes, watched some friends devour them, and dried another two dozen for myself (I have a very small food dryer).

When you eat a dried tomato, it starts out tough and chewy. However, as it softens, the flavor intensifies, and it explodes into a burst of concentrated tomato sweetness. They’re curiously sensational.

Prepare Tomatoes for your Food Dryer

Captions under the photographs explain the steps I took to prepare my tomatoes for the food dryer. Please give this a try and let me know what you think.


Oiling Tomatoes for the Food Dryer

Wash the tomatoes, slice them in half at the equator, and remove the seeds. I removed seeds by gently pressing my pinky finger into each seed pocket thereby squeezing out the seeds and gel into a bowl. Then I filled my food dryer trays with seedless tomato halves, cut-side-up. Finally, I brushed the tomatoes liberally with olive oil.

Note that this was the first time I’d dried tomatoes, and leaving them on a wire rack proved to be a mistake. If such a rack is your only option, cover it with aluminum foil and use the point of a knife to punch a dozen or so slits in the foil.


Seasoning Tomatoes for the Food Dryer

Sprinkle the oily tomatoes lightly with salt, pepper, onion powder, and cayenne pepper.


Tomatoes Ready for the Food Dryer

Slice or chop fresh basil, and add some to each tomato. I had several varieties of basil in my garden, so I used one variety on some tomatoes, and another variety on others.


Tomatoes in the Food Dryer

Set the tomatoes in your food dryer and let them go for 12 to 24 hours. Alternatively, put them in your oven and bake them very slowly—from 180F degrees to 200. They’re done when they’re shriveled and dry (though they’ll be oily, so it’ll be hard to test one without eating it.


Tomatoes from a Food Dryer

The finished tomatoes look like any dried fruit, albeit with seasonings dried in. They’ll keep for several weeks at room-temperature, but eat them before the olive oil on them turns rancid. I’ve heard that some people freeze them, but that seems pointless since you’ve already dried them, and that should preserve them long enough.

Here are some web sites with ideas for how you might use the dehydrated tomatoes you make in your home food dryer. Wherever you see the words “sun dried” in the recipes, substitute an equal portion of your own dried tomatoes:

  • Dairy Max Recipe of the Week: Three Cheese Veggie and Beef Calzone – 1/4 cup sun-dried tomatoes, drained 6 slices (6 ounces) deli roast beef 3 slices Provolone cheese 1/2 cup (2 ounces) reduced-fat shredded Mozzarella cheese 1 (4-ounce) jar roasted red peppers, drained …

  • mio recipe of the week: slow burn sliders! – ½ c. ready to eat sun dried tomatoes, diced ½ c. unsalted or lightly salted cashews, coarsely chopped ½ c. diced red onion (if onion is strong reduce to 1/3 c.) 1 stalk celery, diced ½ c. garden club mayonnaise (where available) …

  • Sundried Tomato Pasta Salad « Let’s Get Cookin’! – At my grocery store, I’ve only found the sun dried tomatoes in a plastic container in the produce section. But you may find them in a jar, packed in oil. If you buy the jarred kind, be sure to drain them well before proceeding. …

  • 2009 May Free Online Recipes Free Recipes – This is one of the best Asian Shrimp dishes I have made in awhile. Szechuan shrimp may indeed even be better than my Szechuan chicken recipe ! A few Chinese shrimp recipes I have tried have been rather disappointing but this was really a hit. Best of all, it calls for precooked shrimp so there is little to no work needed.

Dry Chilies

Posted By: Daniel Gasteiger  //  Category: dry vegetables, food dehydrator, food dryer, food drying

If you want to preserve chili peppers, I encourage you to use your food dryer (if you have one) to dry cut-up sections of larger peppers, or to dry whole fruits of the smaller pepper varieties.

Of course, there are other ways to preserve peppers… here are some thoughts:

Things to Consider about Preserving Chili Peppers

Chilies are among a large selection of foods that you can preserve in many ways. Freezing, drying, canning, pickling, and fermenting are all effective for extending the storability of this fine garden produce.

Store Chilies in your Freezer

Chilies will keep in your freezer for at least a year. The down side of freezing is that it breaks down the cells of the chilies so the vegetables become soggy or mushy when they thaw. When you do freeze chilies, plan to use them for cooking.

Prepare chilies for freezing by dicing them as you might to include in soups, sauces, and stir fry. Then, blanch them by submerging them 3 minutes in boiling water followed by 3 minutes in ice water. Spread the diced peppers one layer deep on baking pans and freeze them overnight. Then transfer the peppers to freezer bags. You’ll be able to take measured amounts of frozen diced peppers from the bags as you need them in your cooking.

Thoughts about Canning Chilies

Canning is a valid way to preserve chili peppers, but the method alters the peppers much as freezing does: canning involves cooking, so canned chili peppers tend to be soft and best to use in cooked foods.

BEWARE! Chilies are low in acid. It’s not safe to can them in a boiling water bath. Rather, to make them safe for long-term storage, you must use a pressure canner. You’ll find useful information about pressure canning vegetables in the article, Pressure Canning from your Home Kitchen Garden.

If you’re not ready to try pressure canning, but you have a lot of chili peppers to manage, consider quick-pickling. Quick-pickling is the process of packing low-acid foods in vinegar and salt brine—and often sugar as well. The brine prevents microbes from growing, and lets you safely seal chilies in canning jars using a boiling water bath canner. My favorite recipe for quick pickling peppers involves making red pepper relish.

Chilies in a Food Drier

Drying chili peppers seems as though it should be a simple task: set them in a warm, dry place and they’ll dehydrate. It’s best practice to blanch chilies before you dehydrate them. So, follow the procedure for blanching that I explained in the freezing section (above).

Spread the blanched chili pieces one layer deep on your food dryer’s trays. It’s OK if the pieces touch, but don’t let them overlap. Set the food dryer’s temperature to 130 degrees Fahrenheit if your dehydrator has a temperature control knob. Let the peppers dry for five hours and check them to see whether they’re dry. To test, remove a piece from the food dryer, let it cool for a minute or two, and bend it until it breaks; it should snap clean like a dry twig. If this doesn’t happen, continue drying the peppers and check them every hour or two until they’re brittle.

When the peppers are dry, turn off the food dryer and let it cool to room temperature. At that point, package the chili peppers in an air-tight container. For longest-term storage, vacuum seal them. To use dried chilies in your cooking, simply add them to wet dishes such as soups and sauces and give them ample time to cook. For drier dishes such as stir-fry, float the dried chilies in boiling hot water and let them cool for ten minutes before adding them to the skillet.

I can’t help but recommend my book, Yes You Can! And Freeze and Dry It, Too for instruction in all types of food preservation. The book provides detailed, step-by-step instructions with full-color photos from my kitchen showing how I preserve vegetables and fruits.
