Every time I see the commercials for Lays flavoured chips, I keep thinking: "What about potato-flavoured chips, eh?"
Every once in a while, I used to pick up a bag of Kettle Brand Krinkle Cuts. They used to taste like potatoes; you used to get a little liquid oil at the bottom of the bag and they tasted great.
After Diamond Foods bought the company, they changed something in how they were cooked. Now they're completely flavourless and taste like, basically, salt.
So now, I have to make my own.
Mandolin-sliced to about 2 mm thick, laid out on parchment paper on cookie sheets, a very thin drizzle of oil, and in the oven for about 30 minutes. As with roasting coffee, you have to watch 'em like a hawk for the last five minutes.
