Wash the fresh tomatoes thoroughly. I like to use a mix of cold water and vinegar. When done use a clean towel to pat them dry.

Cut the tomatoes into thin slices, approximately ¼ inch thick. Try to make the slices as uniform as possible for even drying.

Arrange the tomato slices in a single layer on a dehydrator tray. Make sure there is enough space between the slices for air circulation.

Place the trays in the food dehydrator. I use the Hamilton Beach Digital Food Dehydrator.

The dehydrator should be set to 125F for a minimum of 8 hours.

Let the tomatoes dry for several hours or until they become brittle and crisp. The drying time can vary depending on the thickness of the slices and the humidity levels. It can take anywhere from 8 to 12 hours or longer.

When the tomato slices have finished the drying process and are totally dry, remove them from the dehydrator and allow the dehydrated tomatoes to cool.

Using a coffee grinder or spice grinder, grind the dried tomato slices into a fine powder. Process small batches at a time to achieve a finer powder.

If desired, you can sift the tomato powder through a fine-mesh sieve. This will help to remove any larger clumps and ensure a smoother texture.

Store the tomato powder with a silica gel pack in an airtight container or jar in a cool, dry place.

Wash the whole tomatoes thoroughly. I like to use a mix of water and vinegar. When done use a clean towel to dry tomatoes.

Cut the tomatoes into thin slices, approximately ¼ inch thick. Try to make the slices as uniform as possible for even drying. The thinner the slice the less time it will take to dry.

Arrange the tomato slices in a single layer on a baking sheet lined with parchment paper or a silicone mat. Make sure there is enough space between the slices for air circulation.

Place the trays in the conventional oven.

Turn the oven to its lowest temperature (normally 200F)

Let the tomatoes dry for several hours or until they become brittle and crisp. The drying time can vary depending on the thickness of the slices and the humidity levels. It can take anywhere from 6 to 12 hours or longer.

When the tomato slices are totally dry, remove the dried tomatoes from the oven and allow them to cool.
