1. Place ham slices in a large flat pan and cover with cold water. Let stand 6-8 hours; drain and blot dry. Remove and discard rind. 2. Fry ham slices in single layer in an ungreased heavy skillet over medium-high heat. Fry for 5-6 minutes on each side, then remove to heated platter. Pour off all but about 2 tablespoons fat. Add boiling water and let boil up, scraping bottom to pick up all flavorful bits of ham from the skillet. Stir in coffee. Pour over ham slices and serve at once.
