I bought this little tray at a garage sale. It has slots in it for you to line up potato slices standing up. What you do is slice your potato in one of those miracle slicer thingies, then stand them up in the tray and nuke them for 10-15 minutes. It takes a while for you to get used to just the right amount of time. Too little, and the centres are still rubbery/mushy. Too much time, and they burn. If you do it just right, you have a "potato chip". Now I use this term loosely, because they actually turn out nothing like your garden variety potato chip. But they are yummy. Mind you, you don't get a whole lot of these chips per point, so you have to be really serious about wanting chips. In addition, it is a lot of work. But if you are really really craving that crunch, then these are great!!
