Drying Food 101

Take Your Organic Harvest and DRY IT to Eat All Winter Long

Preserve your summer harvest to enjoy in the wintertime or anytime—without canning. Try your hand at dehydrating your fruits and vegetables. Bet you thought about dried apricots just now!

In our video Dehydrating Food, Tricia shows how to dry fruits and vegetables and make fruit leather. Pretty much no muss, no fuss, if you have a good dehydrator.

How and Why Does Drying Food Work?

Dehydrating or drying food is not a new concept. Our ancestors knew about drying food and early American settlers dried foods such as apples, grapes, corn, and even meat. The concept is simple, organisms that spoil food need moisture to grow. Remove the moisture, the bacteria cannot grow.

What to Dry?

Placing apple slices in the dehydrator

Ripe, unbruised fruits and vegetables. Fruits are easier to dry. Try your hand at drying apples, apricots, pears or grapes. For vegetables dried zucchini, beans or peppers are good for drying. Fruits that are not appropriate for drying are those with a high moisture content like melons or cucumbers.

Most herbs are easily dried. Basil, thyme, oregano, rosemary or sage are a few that come to mind.

What Prep Do I Need to Do?

  • Peel thick-skinned fruits and vegetables, slice uniformly, and remove pits.
  • For waxy small fruits like grapes, blueberries, and cherries you need to create some breaks in the skin coating—do this by “checking” or “cracking” with a 30 second dip in boiling water.
  • Blanch vegetables with steam for 30 seconds, then drop into an ice water bath.
  • To keep apples,pears or apricots from browning, (according to Alabama Cooperative Extension) dip in a citric or ascorbic acid solution before placing on the dehydrator sheet.

Is It Hard to Make Fruit Leather?

Making fruit leather

No, It’s easy!

Puree the fruit in a food processor. Then pour it on a special, non-stick sheet that fits your dehydrator, and spread it with a spatula to a uniform 1/8-inch thickness. The leather will keep longer if placed in the refrigerator or freezer.

How Do I Use the Dehydrator?

Our Excalibur dehydrators come with complete instructions (and an excellent cookbook). Space slices evenly on the rack or you can also use disposable sheets, and start with the time guidelines in the guide and in the university articles or books listed below. Humidity varies, so check your produce during the process. Fruit pieces will be springy and leathery when done; vegetables will be tough or brittle. Fruit leather is ready when it is “leathery” with no sticky spots.

The Nesco dehydrators are a less expensive way to get into drying food. Easy to use on a countertop, due to their round shape, their other major difference from Excalibur is that the fan blows from the bottom instead of the back. Expand the 1,000 watt Gardenmaster Dehydrator up to 30 trays tall. The 500 watt Nesco Snackmaster lets you start dehydrating at a modest price and expands to 12 trays. Both dehydrators in the Nesco line have accessories for making fruit leather and jerky.

I am currently drying kung pao peppers, thai peppers, lemon peppers, red Serrano peppers and ancho peppers by hanging them by fishing line.  They seem to be drying nicely.  Should I worry?

I have lots of onions this year.  How would I safely dehydrate onions?

If you live in a dry region it should be ok. Just keep an eye on them for any mold if you have higher humidity.

You may need to relocate your dehydrator to the garage or have good ventilation, the process can be very “fragrant”.
Onions are easy to dehydrate. Simply peel and cut into 3/8” slices. Place on your dehydrator trays, making sure they don’t overlap. Set the temperature between 125°F and 135°F. Onions will be leathery when fully dried. Drying time should be between 4-12 hours. Refer to your dehydrator’s instructions for more information.

I have successfully dried chopped onion in my Nesco and used them as dried onion flakes in recipes. Very tasty! I have also dried slit cayenne and Thai chili peppers - they should be slit to ensure inner dryness and also speed up the process. I save everything in Ball Jars, shelf or freezer.

Great video!  Now I know what to ask for my birthday.  Thanks for posting “Excalibur Dehydrator” - helps me know what to request.
