Why the “Boston” in Boston Baked Beans

Ever wonder why Boston baked beans are called “Boston” baked beans? It’s the molasses. Boston has been tied to molasses since colonial days when the city was a trade center for rum from the Caribbean. Molasses is used for rum production and is a by-product of sugar refining and was easily available to the colonists.

And then there’s the Boston Molasses Disaster of 1919, when a huge tank of molasses exploded and sent a sea of the gooey stuff flooding the streets of the North End. I lived in the North End of Boston in the early 80s and at the time you could still pick up a faint scent of molasses on a hot summer day.

The Science Behind Slowly Cooking Baked Beans

Now to the baked beans. Boston baked beans are by definition, slowly cooked. According to Shirley Corriher in CookWise (great book, btw), either sugar or calcium will make beans hard, even after long hours of cooking.

Molasses contains both sugar and calcium, which is why adding molasses to a pot of beans will enable you to cook the beans for what seems like forever, without the beans getting mushy. But it also means that if you cook the beans in molasses to get that wonderful flavor, you have to cook them a good long time.

Although traditionally cooked in an oven, Boston baked beans lend themselves perfectly to slow cookers, which is the method we prefer here.

Slow Cooked Boston Baked Beans Recipe

  • Cook time: 8 hours
  • Yield: Serves 5-6 as a main dish or 10-12 as a side

Why pre-soak the beans? You don't have to (see this great Russ Parsons article in the LA Times about why you don't need to soak beans), but not doing so in this recipe will increase the cooking time. With the beans pre-soaked, they'll still take 8 hours to cook and soften in a slow-cooker. Once beans come in contact with the molasses, the sugar in the molasses will keep the beans firm. That's why they take so long to cook.

Ingredients

  • 1 pound (2 to 2 1/4 cups) dry white beans such as Navy beans or Great Northern beans (can also use kidney beans)
  • 1/3 cup molasses
  • 1/3 cup brown sugar
  • 3-4 Tbsp Dijon mustard
  • 1/8 teaspoon ground cloves
  • 3 cups hot water
  • 1/2 pound salt pork (can sub bacon), cut into 1/2-inch to 1-inch pieces
  • 1 medium onion, (1 1/2 cups) chopped

Method

1 Soak beans in water: Place beans in a large pot and cover with 2 inches of water. Soak overnight and drain. Alternatively, bring a pot with the beans covered with 2 inches of water to a boil, remove from heat and let soak for a hour, then drain.

2 Mix molasses, brown sugar, mustard, ground cloves with water: Whisk together the molasses, brown sugar, mustard, and ground cloves with 3 cups of hot water.

3 Add ingredients to slow-cooker, layering them, starting with the salt pork: Line the bottom of a slow-cooker (or a Dutch oven if you are cooking in the oven) with half of the salt pork (pick the fattiest pieces). Layer over with half of the drained beans. Add all of the chopped onion in a layer.

Top with another layer of beans and the remaining salt pork. Pour the molasses water mixture over the beans to just cover the beans.

4 Slow cook until beans are tender: Cover and cook in a slow-cooker on the low setting for 8 hours (or in a 250°F oven), until the beans are tender. Check the water level a few hours in, and if the beans need more water, add some. Add additional salt to taste if needed.

Note that fresher beans will cook faster than older beans. Your beans may be ready in less than 8 hours, or they may take longer. Best the next day.

Serve with Boston brown bread.

    Soaked the beans the night before (which was also the day I bought them). After cooking for 10 hours they are still very hard. The sauce is also thin and weakly flavored. I’m very disappointed. :(

    These sound wonderful! My daughter is a vegetarian so I was wanting to omit the pork. Do you think the recipe will still taste ok? Should anything to enhance the flavor, like liquid smoke?
    Thanks!

    Well I am cooking them in a slow cooker. They have been cooking 7 hours now and are hard as a rock! I soaked them over night and they were covered in water. The beans are new, just bought a few days ago. I even turned slow cooker up high two hours ago and still hard. The slow cooker works fine. I don’t know what to do. Supposed to have dinner in a few hours time.

    3 cups of water may be too much. They came out with too much thin liquid. I was looking for a thicker sauce.
