I was picking through a bunch of recipes I've accumulated in an envelope over the years looking for something different for Thanksgiving or Christmas. I came across a recipe for mortadella-stuffed pork loin. The recipe calls for layers sliced mortadella (could possibly be my favorite food) spread with black truffle butter and then rolled in a butterflied loin of pork. I could probably order the truffle butter over the internet, but I would rather buy it locally. Any suggestions?
