This lady uses a Excalibur for all her dehydrating and has soups listed on her recipes, maybe this will give you some ideas. http://www.dehydrate2store.com/recipes/
She has several listed like potato soup, etc
I can't make premixed due to food allergies, but have been dehydrating like crazy lately and came across her site.
sufficientforme - Thank you- that is a great site! I bookmarked it and am sure I'll keep referring back to it. Love her Q & A list. I just this forum!!
