So I just spent 12 hours trying to dehydrate 6 cups of pasta sauce. Temp was in 170 F (as low as it would go) the oven was cracked open about an inch (i do not have a dehydrator on my oven) and the sauce was still wet on the bottom. I dont think i put too much in there, it was about 1/4- 1/2 inch deep. is is supposed to still be moist?
