1⁄4 cup + 1⁄2 cup water= 6 oz.tomato sauce or 3⁄4 cup tomato paste
I've used a little less water than that and it's a bit thicker.
I've got a bunch of 'pumpkin puree' that I leathered earlier this spring when I first got my dehydrator. I'm going to try powdering that (may need to re-dehydrate a bit first) for use in waffles, bread or vegetable soup stock.
This is a good primer link on veggie powders. I haven't blanched anything just yet but then again I haven't done anything that really needs it so far:

Thanks for the info. Sounds like and interesting and healthy way to save garden produce and money.
Trick for dehydrating tomatoes.
Core then first then Freeze them and then let them thaw at room temperature or do it in the microwave.
Thawing will make the water portion freed up.. Reduces dehydrating time by half. It is messy though.
I slice the semi frozen ones with my dehydrator tray over the sink..
