Dehydrating fresh grape or cherry tomatoes is a very easy way to preserve fresh tomatoes. Dehydrated tomatoes can be used to season all of your favorite tomato dishes, they can be ground into a powder to make tomato powder or rehydrated to add to salads and other recipes. Dehydrated grape tomatoes will last years if stored properly.
Prepare the fresh tomatoes by washing under cold water.
Slice the grape tomatoes in half horizontally.
Line each dehydrator tray with a mesh liner.
Arrange the grape tomato halves on a dehydrator tray cut side down, leaving about ¼ inch between each piece of tomato.
Fill as many trays as you have sliced tomatoes.
Stack the trays following the directions in your dehydrator manual.
If using a dehydrator that has a temperature control setting set the temperature to 125 F. or the vegetable setting. Dehydrate the grape tomatoes for 12 to 18 hours or until the tomatoes pieces are hard, crisp and completely dry. They should not be sticky to the touch.
Allow the tomato pieces to cool completely before storing in an air tight glass jar or container.
Condition the dehydrated grape tomatoes by placing the container away from sunlight in a cabinet or pantry. Shake the jar once a day for one week. Check to make sure no moisture forms on the inside of the jar. If moisture does form immediately return the tomato pieces to the dehydrator to dry completely. If no moisture forms store the container in a cabinet away from sunlight until ready to use.
Store in zip lock bags, or air tight containers. Vacuum seal the jar to extend the storage time for a year or longer.
