That’s why I’m looking into dehydrating....storage space.
I’ve canned (jars) of fruits, veggies and meats and they do tend to take up a lot of space. I like the idea of several pounds of, say tomatoes, transferring into a pint jar - as chopped/slices or as powder (for sauce/paste).
I dehydrate everything out of our garden that isn’t used. I store it all in zip lock bags and freeze it. Uses very little space and tastes totally fresh.
Plus, if you have tomato powder, you can make it as thin or thick as you want. I like to take a couple of small flat bread sandwich rounds, and put tomato sauce with pizza seasoning on it and loads of veggies and cheese for a quick toaster oven pizza for lunch.
Trouble is you only need a tiny bit of sauce out of the cans you can buy. With the powder, you wouldn’t have that problem, and also don’t have to worry about the acid eating through the can.
