How To Dehydrate — Online Reference Guide

AppleThis is a list of 36 of the most common foods dried in an home dehydrator. A food dehydrator is one of the easiest appliances to operate, and most recipes are very simple and similar.

Before we get to the list, here are some common instructions that many of the foods below share.

Pre-Treatment

If the instructions say to pre-treat, that means to dip the fruit in ascorbic acid, citrus juice, or simple syrup. This is because some fruits will brown when exposed to air, and pre-treating will prevent discoloration.

To make a simple syrup, boil water and sugar in a 1:1 ratio. Let it cool before using it on the fruit.

For vegetables, you'll need to steam blanch for about a minute. This helps to prevent spoilage while in the dehydrator and also softens the cell structure to allow water to escape quicker.

Water blanching is not recommended because the vegetables will lose much of their vitamins and minerals.

Drying Times

You'll know the food is dry by touching and breaking a piece. There should be no moisture inside or out. The total drying time for each food depends on the food thickness, humidity, your food dehydrator, and your personal preference for taste and texture.

Knife or Mandoline

I recommend using a mandoline if your knife skills aren't good. You want to have uniform pieces so they all dry evenly. Some vegetables, such as sweet potatoes, work best when very thin, so a good food slicer is a worthy investment.

Two Fruit Drying Strategies

For all fruits, there are two basic recipes. The first, which is a little less convenient, involves two drying temperatures. You would start at high (about 145 degrees F) for 2 hours, and then finish at a lower temperature, such as 105.

The second, which I prefer, is to dry at a medium-high temperature like 135 and leave it alone. It's more convenient and the finished product tastes as good as the other way like this.

  21. Morel MushroomHow to Dehydrate Mushrooms
    Depending on the mushroom, you may or may not cut them into or 1/4" slices. Some, like Matsutake and pine mushrooms, are suited for slicing. If you had a morel however, you'd cut it in half lengthwise. If it's really large, you can cut it again to make future storage and use easier.

    Dry at 135 degrees for 4-8 hours. I've seen recipes that say you should dry at 90 for 2 hours and then finish at a higher temp. I prefer the "set it and forget it" nature of the single temperature recipe so I stick with that.

    Drying is the best method of preserving mushrooms. They'll store for months, and using them is simple. Rehydrate them by soaking in warm water until soft. If you're using them in soups or stews, you can drop them in the pot without rehydration. You can try them in egg omelets, sandwiches, and pasta dishes.
