Hazelnut and butter pasta sauce

This is the essence of decadence. Put a stick of butter in a pan over the lowest possible heat, and allow it to heat until it begins to acquire a bit of color; it should smell nutty and delicious. Chop some hazelnuts finely, and turn the heat off the butter. Add the hazelnuts. Stir, add a dash of pepper, pour over your favorite pasta, and top off with parmigiano reggianito.
