My Excalibur food dehydrator came last week and I have been anxious to try it out. I decided that I would give it a test run on some onions. My favorite onion is the Vidalia Onion. So, I sliced the onion into 1/4 slices and then quartered the slices. Placed them in the dehydrator until dry (hard) and ground them up in my designated coffee grinder. WOOHOO!!! The best tasting onion powder I have ever had, way way better that the store bought variety.
