Maine baked beans is a traditional dish originating from the state of Maine. It is made with a combination of Maine dry beans (usually of the Yellow Eye variety), salt pork, sugar, molasses, mustard, onion, salt, and pepper. The beans are soaked overnight, then parboiled in the morning up to the point when their skins crack when blown upon.
The onion is cut and placed on the bottom of the pan, followed by beans and salt pork on top. A combination of other ingredients is then poured over the pork and beans. The whole pot is then placed in the oven and slowly baked, typically for 6 hours or more.
