Truffled Potato Gratin and Wild Boar Ragu

The first time I shopped at Wegmans, I noticed the truffles in the produce aisle.  They were locked in a plastic case and at the time it was really strange to me. Who on earth would spend that much money on a mushroom?! I think I'd tried something with a truffle in it once or twice and wrote them off as insanely pricey.  As the years went by, I got more curious but never actively searched for something to make with them.  A few years ago, some friends invited us over for dinner and they served truffled potato gratin.  It was amazing!  My husband and I promised we'd make it ourselves and then we never did.  Last week, my in laws came to visit and we decided to cook for them instead of going out.  It was the perfect excuse to make the potatoes.  They aren't healthy.  They're expensive.  They're fabulous.  

Sprinkle liberally with Lipitor before serving
