Michel Rostang's $122 Sandwich (Yes, Truffles)

It seems whenever there's some kind of exorbitantly expensive food there's an ingredient that almost always makes an appearance: truffles. This sandwich, called LE "SANDWICH" TIEDE A LA TRUFFE FRAÎCHE, and created by French chef Michel Rostang, is no exception. It will appeal to purists mostly as it is amazingly simple: fresh truffles are sliced and placed on toasted country bread with salted butter. The sandwich sits for two nights (so the flavors can marinate together) and then the whole thing is lightly grilled on both sides. That's it. Heck, if you have some spare truffles lying around you can make this at home instead of a grilled cheese or something. Or maybe not. 98 €
