The results might look like some kind of fancy sugary confection, but this detailed Instructable shows you how to make a see-through snack that tastes exactly like potato chips. Minus the fat, greasy fingers and guilt.
The recipe does call for potatoes, but they're actually used to create a flavoured stock along with potato starch and gelatine. Just make sure you can dedicate quite a bit of time to the process, which includes baking the chips for 8-10 hours before the gelatine chips are fried. The results are remarkably impressive and supposedly taste exactly like the real thing.
