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!
My sister bought one of these recently. I have the really old round one. One thing I like to do with it is this.
Marinate 1/2 pear or cherry tomatoes in olive oil, garlic and herbs drain them then dehydrate them. Tasty in salads, pasta or whatever.
I have been using my excaliber dehydrator as a yogurt maker for years. It has been too hot here so I tried putting the yogurt into a ice chest with extra padding inside to keep in the heat - and it worked! Yogurt is only a tiny bit softer than if I had used 7 hours of electricity!
