Mmmm. Home-grown tomatoes. Sweet, ripe, red, organic....If only they would last all year! Well, they can. And it won't cost you anything but a few minutes, either.
Wash, core and quarter the tomatoes lengthwise. (A paste tomato, like the Roma above, will work best.) Lay peel side down on dehydrator trays and dry until leathery. The drying time depends on the type of tomatoes you have, how full the trays are, the humidity in the air and the heat setting of your food dryer. A rough estimate is 6 hours at 140 degrees, 8 hours at 125 degrees or 12 hours at 115 degrees. Lower temperatures preserve enzymes and vitamins but expend more electricity.
