Make Sundried Tomatoes in Your Car


No Fuss Sundried Tomatoes Dehydrated in Your Car

Folks, I know you're gonna love this one. Yes, you can make gourmet sun-dried tomatoes in your car!

Fresh sun-dried tomatoes retail for $5, $10, or even $20 a pound. Whether you grow your own tomatoes or take advantage of seasonal sales, making your own sun-dried tomatoes is hands-down the easiest way to preserve the bounty of the season.

When it's too hot to drive, take advantage of the summer heat and preserve tomatoes. In the middle of winter or before the next harvest, there's nothing like the delicious sourness, saltiness and rich flavor of sun-dried tomatoes. Tomatoes of all sizes from cherry to beefsteak can be sun-dried in the car in a few days. Unlike sauces and soups that require tomatoes to be blanched, peeled, and cooked extensively, sun-dried tomatoes need only be sliced, salted and placed in the car for passive solar drying and long-term preservation. I hope you enjoy this new take on an age-old technique.

History of the Sundried Tomato

Origin of the Fruit and Preservation Methods

The sun-dried tomato or pomodori secchi is a one of the specialty ingredients used by gourmet cooks and Italian restaurants. Although tomatoes are associated with Italian foods, they are native to South America, which means there was probably salsa before pasta sauce.

The tomato was brought back to the old world and introduced to the Mediterranean in the 1500s by the Spanish Conquistadors.


Because the first tomatoes brought to Europe were golden yellow, pomodoro, which is the Italian word for tomato, literally means golden apple. In the 1600s, the tomato was first described in the English language using the name love apple, a term that stems from French pomme d'amour a possible corruption of the original Spanish word for tomato, which was pome dei moro or apple of the Moors.

The archetypal red tomato was unknown in Europe until Jesuit priests brought seeds on their return trip from missionary work in Mexico. The modern word tomato originates from tomati which is the name used by tribes in Central America. When the tomato was first introduced, many people believed it was possibly poisonous because it is a member of the solanacae or nightshade family. Until the 1800s, cookbooks instructed a minimum three hours of cooking time to eliminate the raw taste. Today, it's hard to imagine a fruit or vegetable that is loved more.

Before the days of electricity, canning, and modern food preservation,


sun-drying would have been one of the preferred preservation methods. Commercial manufacturers hire workers to spread tons of machine cut tomatoes on the ground or on elevated tables with mesh screens. Outdoors sun-dried tomatoes take about one week to fully cure depending on the humidity and temperature. The processing of dry tomatoes by removing the water and curing with salt can also be achieved in the car or in standard household oven on the lowest setting.

Ingredients and Supplies

Not too many, but you will need:

  • Fresh tomatoes one pound or more
  • One cup of Kosher salt
  • Baking dish
  • Cutting board
  • One very sharp paring knife
  • Cheesecloth (optional)
  • Herbs (optional)

Sun-dried tomatoes provide pure, intensified flavor. For the best results, use vine-ripened tomatoes which are the most flavorful. Because tomatoes have more than 80% water content, it takes a few pounds to make a substantial quantity of sun-dried tomatoes.

Salt is the second most important ingredient for sun-dried tomatoes. Salt acts a desiccant and preservative that pulls water from the fruit and prevents mold or bacterial growth. I prefer Kosher salt for several reasons: It's made from pure sea salt, it's economical, and the large flakes seem to be more effective. Salt will be applied several times throughout the drying process for a pleasantly salty finished product, however the majority of the salt will be washed off by the tomato water.

To dry your tomatoes, use a non-reactive baking dish preferably made from glass. Pyrex dishes and pie plates work great because the sides are high and they're easy to pour from.

Cheesecloth is completely optional. Inside the car there is very little risk for bug infestation compared to drying outside. Cheesecloth can also make it easier to pour of the water without losing any tomatoes. If you choose cheesecloth, you'll need several large, strong rubber bands and some other makeshift devices, such as binder clips, to hold the cheesecloth without letting it drape in the tomatoes.


Sundried Tomato Preparation

1. Wash tomatoes to remove any surface dirt from the skin.

2. Cut tomatoes in halves or quarters. (removing the seeds and gel is not necessary. In fact, much of the tomato's flavor is retained in gooey liquid that surrounds the seeds.)

3.Arrange tomato pieces across the baking dish as tightly as possible. The tomato pieces will shrink dramatically and shift so it's not important to be precise.

4.Salt liberally until all of the piece are coated with a thin layer of salt.

5.Place baking dishes in a sunny part of your automobile, such as the dashboard or rear window of a hatch-back station wagon.

After 2-4 hours check the tomato pieces and drain off water as necessary. I have found the most dramatic water-loss occurs in the first eight hours, so draining the dishes frequently during the first day is extremely important. At night, bring your trays inside and dose liberally with salt. I find it's convenient to store the drying tomatoes in the oven where they are out of the way. As the tomatoes begin to dry, your will notice the raw smell fading and a delicious, tomatoey sweetness developing. Once the majority of the water has drained off, you can add thyme, oregano and other complementary herbs if desired.

If the sun decides to hide while you're drying your tomatoes, simply bring the baking dishes inside and dry inside the oven with the lowest setting, which is approximately 150 to 200 degrees. If any strong odors develop while oven drying, turn the heat off and allow the oven to cool briefly. On average, it take approximately 5 to 7 days before the sundried tomatoes lose their tackiness. The ideal moisture levels allow the sundried tomatoes to remain supple without supplying enough moisture for spoilage to occur. When in doubt, allow the tomatoes to dry further. Removing too much moisture will make the sundried tomatoes brittle. However, it's better to err on the side of dryness.

Once the drying process is complete, simple store the sundried tomatoes pieces in a glass jar with a tight fitting lid. To prevent excess moisture, I add one silica desiccant packet to each jar. Although it's unsafe to eat silica pack, they are excellent for prevent moisture buildup in the packaging of moisture sensitive food products. Once dried, tomatoes have an extremely long shelflife. Add a cut ribbon or decorative cloth cover, and gift your sundried tomatoes to someone special.

Who knew that something that taste so incredibly good could be so nutritious? The best is sun drying in the car instead of building a screen drying frame. Totally cool. I have to try this! *Squid Angel Blessed* and pinned to my "Stocking Up" board.
