Step 1

Slice your tomatoes as thinly as possible.

Step 2

Space your tomato slices on a rack in the dehydrator at 120-140F. Alternatively, place in your oven at the lowest temperature it will go.

Step 3

After 5 hours, check on your tomato slices. You'll want the slices to be completely dry. When you try to bend them, you'll want them to snap like a crisp, not bend. If they are not dry yet, place back in the oven or dehydrator and check again an hour later.

Step 4

Once completely dry, add your dried slices to a blender or food processor and blend or process until you are left with a fine powder.

Step 5

Sift through a mesh sieve to separate the larger pieces and then blend the larger pieces again.

Step 6

Pour your tomato powder into an airtight container for storage. Optionally, add salt to preserve for longer and add flavor. I recommend 1/4 tsp for every 1/4 cup of tomato powder.
