This is a recipe similar to the one my mother used to make when she wanted long cooked baked beans. In Maine they actually dig a big hole and fill it with coals from a fire and then set the pot in the hole and cover it with more coals and dirt for 6-8 hours or overnight. Cooked Low and slow is the way to go.
Soak beans overnight. Drain and place into large 6 qt or more Dutch oven or heavy roaster. Add remaining ingredients and stir. Add sufficient water to cover the beans by at least 1 - 1 1/2 inches and stir well.
Place covered Dutch oven in preheated 250 degree oven and bake for 6-8 hours. Check periodically to see if they need more liquid and to see if the beans are done to your liking (after at least three to four hours). Continue to cook til the beans are soft but not falling apart.
If they are too liquidy, remove cover and bake for about 30 minutes. If too dry, stir in a little water and let absorb.
Serve with your favorite picnic foods like fried chicken and coleslaw and buttered bread.
