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.
