Boston baked beans

Soak one quart of beans over night in warm—not hot—water. In the morning cook them until the skin curls on a bean when you blow upon it. Pack them in an earthen pot. Score the skin of a pound of streaked salt pork, and almost bury it in the beans. Pour over this one dessertspoonful of molasses, mixed with as much vinegar, a good pinch of pepper and a teaspoonful of mixed mustard. Cover closely and bake six hours in a good oven.
