I love dehydrating food from the garden. No waste here at the homestead. I had garlic bulbs that needed used up and red onions so I dehydrated them for shelf stable powder and left 1 jar on onions to rehydrate in soup and such later down the road. I sliced about 1/8 to 1/4 inch and dehydrated at 130 degrees for about 24 hours. Then used my food processor to grind into a powder. More seasonings to my pantry with just the cost of some of my time.
