Being a country girl, I haven't been to Boston since 2005. But if this is how beans and rice rolls there, then lucky them. I adapted this recipe from The Moosewood, and I'm guessing they called it "Boston" because the molasses makes it taste like baked beans, but way more interesting.
I was really excited by this recipe because I am always trying to expand my bean repertoire. These beans don't have anything spicy (although that can be remedied at time of eating by some Garlic Tabasco Sauce), but they do have mustard and tamari. And if that's not salty enough, you can serve them with rice pilaf from a box like I did.
