Dried cherries are a tasty, portable and healthy snack. They can also be used in baked goods, as a salad topping, and in compotes. Keep in mind that the more flavorful the fresh cherries you start out with, the more delicious the dehydrated version will be.
Wash and Stem the Cherries
Wash the cherries and let them drain in a colander for a few minutes. Remove and discard the stems.
Pit the Cherries
No question about it: this is the most tedious part of any cherry recipe or preservation method. But there are ways to make the job easier.
You could buy a cherry pitter. These are inexpensive gadgets that can also be used to pit olives. But save your money, because I'm going to tell you two different ways to make your own DIY cherry pitter.
The Beer Bottle Pitter
All you need is a beer or wine bottle, cherries, and a chopstick. Place a cherry, stem end up (but with the stem already removed), on the opening of the bottle. Punch it with the chopstick. The pit will fall into the bottle while the rest of the cherry remains where it was.
The Drinking Straw Pitter
Hold a cherry between your thumb and forefinger with the stem end facing up (stem already removed). Punch out the pit with a plastic drinking straw. The pit will go into the straw. Repeat with more cherries until the straw has filled with pits. To continue pitting more cherries, either empty out the straw or use a new one.
Arrange the Cherries on the Dehydrator Trays
Arrange the cherries on the dehydrator trays so that there is space surrounding each piece of fruit.
Dry the Cherries
Set the dehydrator's temperature to 165F/74C. Some dehydrators don't go this high: if that's the case with yours, use the highest temperature you can. Dry the cherries at this temperature for 2 - 3 hours.
Lower the temperature to 135 F/57 C and dry the cherries for an additional 10 - 20 hours, depending on the size of the cherries. The cherries should feel totally dry to the touch, but still be leathery and somewhat pliable.
Cool the Dried Cherries
You won't be completely sure if the cherries are fully dehydrated until they have cooled (you know how cookies crisp up after you take them out of the oven? Same deal with dried fruit). Turn off the dehydrator and open it. Let the cherries cool on the trays for 20 to 30 minutes.
After the cooling off period, break one of the cherries in half. There should be no visible moisture along the surface of the break.
Condition the Dried Cherries
Even after the cherries are correctly dehydrated there may still be some residual moisture in the fruit that you can't feel. This shouldn't be enough to prevent the fruit from being safely preserved and mold-free. But you'll have a tastier, better product if you do what is called "conditioning" the dried fruit.
Put the dried, cooled cherries into glass jars, only filling the jars about 2/3 full. Cover the jars. Shake the jars a couple of times a day for one week. This redistributes the cherries as well as any moisture they may still contain. If any condensation shows up on the sides of the jars, your fruit isn't dried well enough yet and it needs to go back into the dehydrator for a few hours.
Once your dried cherries are conditioned, store them in airtight containers away from direct light or heat. It's okay to fully fill the jars at this point: the 2/3 full was just for the conditioning phase when you needed to be able to shake the pieces around.
