Epazote what??

Last night, my sister and I took a Mexican cooking class. We made some wonderful corn guacamole, an interesting poblano, spinach, and black bean lasagna with goat cheese, a flavorful chicken pilbil, and a decadent chocolate mousse. The most interesting thing I learned in the class was that people often use the herb, epazote, in recipes with black beans to ward off the evil effects aka gas. Perhaps, I'm the only one who didn't know this but it's helpful nonetheless!
