Makes 8 servings.
Preheat oven to 250 degrees F.
In medium ovenproof pot over medium heat, cook one piece of scored salt pork until fat renders, 3 to 4 minutes. Add onions and sauté until beginning to color, 10 minutes. Add beans.
In medium saucepan over medium-high heat, combine water and remaining ingredients. Bring to boil, pour over beans and stir. Place remaining piece of salt pork on top. Cover pot and place in 250-degree F. oven. Bake 5 hours, checking each hour to make sure beans do not dry. Stir in additional water, ½ cup at a time, if beans are dry. Uncover and bake 30 minutes. Remove from oven, cube pork and serve beans topped with pork. Pass a basket of warm Minnesota blue bread.
