Bring roast to room temperature; place in open baking pan (I recommend an old-fashioned iron skillet). Liberally shake soy or Worcestershire sauce, letting some collect in bottom of pan. Salt lightly all over, pepper heavily. Add 2 - 4 cups of water.

Place, uncovered in preheated oven, and cook 7 minutes per pound, turn oven off, and do not open oven door for 2 hours. The roast at serving time will be pink and delicious.
