Fill a big bowl with lukewarm water and drop the beans in. Leave them to soak overnight at room temp, adding more water if needed so they stay covered. Drain and rinse well when you're ready to use them.
02 -
Set one of your oven racks to the middle and heat it to 250 °F (120 °C).
03 -
Mix everything—beans, onions, tomatoes, bacon, salted pork, ketchup, molasses, sugar, balsamic vinegar, mustard, salt, and pepper—in a 4.5-liter oven-safe pot or Dutch oven.
04 -
Pour enough cold water into the pot to cover the beans by about 2 inches. Bring it to a boil over medium heat.
05 -
Take the pot off the stove, cover it, and let it bake in the oven for about 7 hours. Stir it every hour, adding extra water if it looks dry. By the end, the beans should be soft and fully cooked.
