Step-by-Step Process

Step 1: Prepare Your Tomatoes

When it comes to preparing your tomatoes for dehydration, there’s no one-size-fits-all approach. It’s ultimately up to you how you want to prepare them. If you look at canned tomatoes, you’ll notice that the skins and seeds are typically included.

Not everyone prefers this method, but it is a way of retaining as much of the tomato’s nutrients as possible. Plus, if you don’t mind the texture, it saves a significant amount of time.

Personally, I like to keep things simple and straightforward. I don’t peel the tomatoes or remove the seeds — just like when I can my tomatoes. Here’s how I do it:

  1. Start with the tomatoes you’ve freshly picked from your garden. Ensure that they’re ripe and free of blemishes.
  2. Take a silicon mat or any similar material. This mat helps to prevent a mess when dealing with liquid ingredients like tomatoes.
  3. Slice your tomatoes into manageable pieces and toss them into the blender.
  4. You don’t want your blender to get clogged up, so be sure to add the tomatoes gradually while using the ice crusher setting on your blender.
  5. Once all the tomatoes are in, you can switch to the liquefy setting to get a smooth mixture.

Step 2: Blend Your Tomatoes

Add your sliced tomatoes to your blender or food processor. Using a pulsing or crushing mode, blend until your tomatoes turn into a liquid consistency.

Step 3: Prepare Your Dehydrator Trays

Before pouring your tomato liquid onto your dehydrator trays, consider lightly coating the trays with a bit of avocado oil (or another healthy oil you have on hand).

While not absolutely necessary, this step can prevent sticking and make your flakes easier to remove once dehydrated.

Step 4: Spreading the Tomato Mixture onto Dehydrator Trays

After blending your tomatoes, the next step is to spread the mixture onto your dehydrator trays. Here’s how:

  1. Pour the tomato blend onto your trays. Be careful not to overfill the trays — it can lead to spills and messes.
  2. Use a spatula to smooth out the mixture, ensuring an even spread across the tray.
  3. Repeat the process for the other trays.

Step 5: Dehydrating the Tomatoes

The actual dehydration process is what will turn your tomato mixture into flakes. Here’s how you do it:

  1. Set your dehydrator to 135 degrees Fahrenheit.
  2. Place your trays into the dehydrator.
  3. Dehydrating tomatoes can take quite a few hours. Instead of setting a timer, you should keep checking on your tomatoes throughout the day.

Step 6: Store Your Tomato Flakes

After your tomato liquid is fully dehydrated, remove it from the trays. It should come off easily, especially if you’ve used a bit of oil. Break the dehydrated tomatoes into smaller flakes.

Store these flakes in a jar, using a pestle or a similar tool to tamp them down and save space. If you prefer tomato powder instead of flakes, you can pulverize them further using a blender or food processor before storing them.

A Note on Vacuum Sealing

If you’re planning on vacuum sealing your tomato flakes, make sure to use a previously used lid. Place the food saver top onto the jar and use a hand pump to create a vacuum inside. Once the gauge reaches 15, you can remove the top. Your jar should now be vacuum-sealed.

When you’re ready to label your jar, use rubbing alcohol to clean off any old labeling and write the new label with a permanent marker. This method ensures that your labels are always accurate and up-to-date.

Additional Tips

While these tomato flakes work perfectly as they are, you can also turn them into a powder form. This powder takes up less room in storage and works as a great thickening agent for sauces. However, keep in mind that making a powder will require additional clean-up.

Remember to always store your jar in a cool, dry place for longevity. It’s also important to ensure that your jar is sealed correctly to preserve the freshness of your tomato flakes.
