I haven't been able to find any instructions online or in the cook books I own regarding drying Kiwi. I'm making it up as I go. I currently have 5 racks of kiwi (appx 50 small) peeled and sliced about 1/4 inch thick with my dehydrator set at about 135 F. I did not sweeten them or dip them in citric acid as some websites say is done commercially. I started them about 6:50 PM. I'll dry them overnight and see how they go... It's a work in progress. Has anyone ever dried kiwi before?
Update: I was able to take off the majority of the kiwi (all but about 1.5 trays worth) at 8:30 AM. That's a total of about 13.5 hours of dry time. The remaining kiwi slices were a little thicker and stayed in the dryer until about 12:30 PM, so an additional 3 hours or so. They are tasty, a little tart, but still have a great kiwi taste. I'm sure you could do this in the oven, but you will not be able to do as many.
The 50 small kiwi I used made about 9.5 ounces of dried Kiwi. If you try this, let me know how it goes!
