Brazilian Black beans

4 cups black beans
1/2 lb piece beef chunk
1/2 lb salt pork, sliced
2 teaspoons olive oil
1/2 cup chopped onion
2 cloves garlic, minced
salt & freshly ground pepper

Wash beans, cover with water and soak overnight. The next day
drain and transfer to a large, heavy kettle. Add enough cold water
to come about 2 inches above the beans. Bring to a boil, add the
beef, salt pork. Lower the heat and simmer uncovered for three hours, stirring occasionally. Cool and discard the meats.
Heat the olive oil in a skillet, add the onion and the garlic and cook until the onion is tender. Stir into beans. Cover and refrigerate overnight. To serve, heat for an hour, stirring occasionally. Adjust seasonings.
