This is my attempt to re-create the beans at my favorite burrito place, Tortillas, in Atlanta GA. Unfortunately, they closed, so now I have to try to make my own burritos, because no other establishment makes a burrito that measures up. Also, I now live in NYC, which is a burrito desert. Do not pre-soak your beans. If you do this, they will already have absorbed a bunch of water and will not be able to absorb all the flavors from the spices and broth. Do not worry about the salt added at the beginning, it is an old wives' tale that beans will be tough if you add salt at the beginning. You want to add all the spices and seasonings at the start so the beans will absorb them.
