In a large skillet, brown the ground beef
until all the pink is gone, about 10 minutes.
Add the beans to a large pot and cover with 3 quarts cold water. Add the onion
, salt pork
, sugar, chili powder and salt. Bring the beans to a simmer over medium-high heat. Add the cooked beef and simmer
until the beans are tender and the liquid has thickened slightly, about 2 hours. Serve hot as a side dish.
