Score the bacon in squares without cutting through the rind. Put half the beans in the pot in which you will bake them and add onion, molasses and seasonings. Add remaining beans and bury the bacon, rind up, in the top layer. Add just enough boiling water to cover. Cover the pot tightly and bake at 300° F for 4-6 hours or more to melt the pork fat and meld the flavors. Add boiling water from time to time if needed. Remove lid for the last 30 minutes to make a brown crust.
