These instructions are copied directly from that site, so I pass on all credit to her. This is just my review of the process.
(makes 4 servings, 12-14 chips each)
1 1/3 pounds Yukon Gold or red potatoes, unpeeled, scrubbed
2 teaspoons or so of extra-virgin olive oil
1/2 teaspoon salt
Cooking spray
Slice potatoes into 1/8-inch rounds for thicker potato chips. For thinner ones, use a mandolin to cut very thin slices. Toss slices in a medium bowl with oil and salt to coat evenly.
Coat a large microwave-proof plate with cooking spray. Arrange some potato slices in a single layer on the plate. Microwave, uncovered, on High until some slices start to brown, 2 to 3 minutes (depending upon potato thickness and microwave power). Turn slices over (they will be hot, so take care with your fingers) and continue microwaving until they start to crisp and brown around the edges, about 35 seconds for very thin potato slices to 2 to 4 minutes for thicker slices. Check frequently and rearrange slices as needed to prevent scorching. Transfer chips to another plate and allow to cool completely. (They will crisp up more as they cool.) Repeat process with remaining slices.
Storage: Store in an airtight container for up to 3 days.
I started with three potatoes and tried to use the slicer side of my grater. I probably spent a dollar on that grater and this is a case of where you get what you pay for. It's fine for grating cheese, not so much for the slicing option. So I tried to slice them thinly with a knife, but they just don't end up as even. If you want to make these and you want a thin chip, definitely use a mandolin.
For the first round I did forget to spray the plate and that does seem to make a difference for some reason. It took me three plates to do all the slices I had. I thought it would be a fairly quick process, but it's totally not. It probably took 45 minutes from start to finish! By the time you slice the potatoes, coat them, microwave, flip, microwave some more, flip the ones that aren't quite done and put them back in.... And all I got was one small bowl of chips! OK, plus the few I had to try during the process. So even going slow and trying to savour each bite, it took me about 8 minutes to eat them all.
They turned out alright, though some of the thicker ones were still a little chewy. Overall, I'd say they're more like a kettle chip than a standard chip.
From the recipe I used, I'm going to say who really wants only 12 chips? If you've been eating healthy and decided to finally cave, 12 is not going to make you happy. And why would you make them to store them? One of the benefits of making them at home is that they're still a little bit warm from being cooked.
To be honest, it wasn't worth my time. It would have been faster for me to drive down to the grocery store and spend the money for some chips made by the companies that have this process nailed down. And then if I've got some willpower, I actually have some left over to enjoy another day. It's what I ended up doing anyway since I was a little disappointed in how these turned out :)
