Tomato powder is very easy to make. You can us your own canned tomatoes .Fresh or store canned tomatoes work just as well.
If your using fresh tomatoes just cut them thin and place in a single layer in your food dehydrate . For canned tomatoes place in a blender or food processor and blend.
For blended tomatoes you will also need to use a fruit roll screen or parchment paper on your trays. Pour a thin layer of your blended tomatoes on your trays. Dehydrate over night till both your fresh and blended tomatoes are dry and is easy to crumble. ( Humidity and temp will play a factor in your drying time.)
After cooled and crumbled, place in a coffee grounder or some type of blender. Blend till you have a nice powder. I place my power in a Ziploc bag with a oxygen absorber.
For tomato puree 1 part powder to 1 part water.
For tomato sauce 1 part power to 2 parts water.
mix together and let sit 1 to 2 minutes to fully rehydrate.
This powder is great for making dried hiking meals . They taste so much better and way cheaper. You can also use it for long storage meals.
