Swedish brewery S:t Eriks created a box of fancy potato chips that costs 499 kr (~$56). There are five chips in each box. Obviously a marketing/fundraising gimmick, but they certainly sound like quite the artisanal chip. Ingredients include: matsutake, truffle seaweed, crown dill, Leksand onion, India Pale Ale wort, and potatoes gathered from a "hillside in Ammarnäs, a steep, stony slope in a south-facing location where almond potatoes are cultivated in very limited numbers."
They made just 100 boxes and sadly they have all sold out (with proceeds going to charity). Oh well, there are always Pringles.
