How to Make It
Preheat oven to 300°F. Bring cold water to a boil in a heavy-bottomed Dutch oven over high. Add beans and salt, and return to a simmer. Cover and transfer Dutch oven to preheated oven. Cook until beans are tender, about 1 hour and 10 minutes, checking after 30 minutes to ensure beans are still covered with water. If necessary, add just enough water to cover.
