Once raviolis begin to boil, begin making the butter sauce. Place the stick of butter in the center of a 12″ saute’ pan and melt on medium high. Once the butter starts to get frothy, stir in sage leaves (they will fry in the butter), nutmeg, salt and pepper. Continue cooking for about 1-2 minutes until it is caramel in color and nutty. Pour sauce over raviolis, sprinkle with toasted pine nuts and serve immediately.
