The day before place beans in a large cooking pot, cover with 8 cups of water and let them soak for 12 hours or overnight.
The next day, drain the beans. Cover them with fresh water and bring the water to a boil. Reduce the heat and simmer the beans, uncovered, for 45 minutes to 1 hour.
Meanwhile, place the salt pork chunks in a bowl and cover them with boiling water. Let sit for 5 minutes.
Preheat the oven to 300° F (150*C).
In a large bean pot with a lid or similar oven-proof cooking vessel, combine the beans, along with their cooking liquid, beer, onion, barbecue sauce, brown sugar, molasses, vinegar, mustard, salt, ginger, cloves and bay leaf. Mix well. Drain the chunks of salt pork and place each one in a different area of the bean mixture. Cover the pot and place in the preheated oven.
Bake the beans for 5 hours, stirring every 30 to 45 minutes. The beans should remain covered with liquid as they cook; add more water as necessary to keep them covered.
Remove the cover from the beans. Bake them for 1 hour more, or until a crust on top forms, but without allowing the beans to become too dry.
Makes: (about 2 quarts of beans), enough to serve 6 to 8
