See the tomatoes in the dehydrator? You'll notice there isn't a photo of them in the jar after being dehydrated. I forgot to poke holes in them. You MUST pierce the skin of any globe shaped fruit/vegetable before you dehydrate them. These were at the tail end of the garden production, so those tomatoes were really about to rot. Not piercing them gave them just enough time to go bad. Ruined.
Really frustrating to make that kind of mistake; dried tomatoes are so great. The drying process eliminates the water content (obviously), and as a result the sugars come to the front of the flavor. Put a little ground pepper on tomatoes before drying for a spicier end product. Not only are they great in soups and stews, but even my kids will eat dehydrated tomatoes because they are so sweet.
Good thing I still have some from last year!!
