A month or so ago I purchased a Nesco Dehydrator with 7 trays, last week I went to the website and bought an additional 4 trays with removable centers. I love finding all the things I can use this for, I already have dehydrated apples, carrots, cucumbers, herbs, zuke, squash, raisin's and citrus. I've made jerky (anyone have a great recipe or tips?) made dog treats, dried gumpaste flowers and real flowers to collect the seeds, proofed bread and now I'm using it as a yogurt maker. I can honestly say this has been the best purchase I've made in ages!
