I also have the Excalibur (9 tray) and love it! I'm currently dehydrating a jar of spaghetti sauce for our next trip... like tomato's, i'm going to dry it till crispy then powder it in the food processor... its amazing how well that works!

I would highly recommend dehydrating your veggies/fruits before adding everything together. Also, rehydrate your food before you add salt, it will rehydrate faster.

Other things like rice dehydrate nice as well... cook it + dehydrate it = healthy instant rice!
