Mohawk Baked Beans

Place the beans in a large pot and cover them with cold water. Soak them overnight. Drain and rinse the beans. Put the beans in a Dutch oven or oven-safe pot and cover them with water. Bring them to a boil over medium-high heat, then reduce the heat to low and simmer for 1 to 1 1⁄2 hours, until the beans are fully cooked, but firm. Once the beans are fully cooked, but firm, add the onion, maple syrup, tomato paste, and mustard. Stir in a teaspoon of salt and pepper. Put them in the oven, uncovered, and set the oven to 225°F (105°C). Let the beans cook 8 hours or overnight, checking occasionally and adding water if needed. Adjust the salt and pepper to taste. Serve hot.
