Preheat oven to 350 degrees. Drain beans, place in an ungreased 3 litre bean pot or casserole, and mix in all remaining ingredients. Cover tightly (use a double thickness of foil if casserole has no lid) and bake 5 to 6 hours, stirring occasionally, until beans are tender and sauce thick. If mixture gets too dry before beans are done, stir in a little warm water.
