There was a time when my gardens produced way more tomatoes than I could use or give away. Sort of a good news/bad news type of thing. I tried juicing them and freezing them which worked but took up a lot of space in the freezer. Then along came dehydrating.
This works best with the fleshier varieties like Roma, Early Girl and some cherry tomato varieties. Dehydrate the tomatoes till you can put them in a blender and pulverize them to powder.
You can save all your production in a minimum of space and just add water to make tomato paste, soup, sauce, etc. And, if you want to get creative, dehydrate some seasonngs and add them to the powdered tomato and you can have instant whatever; sauce, paste, soup or Bloody Mary mix. (Need a bit of celery for that)
Cheers!
