Rancho Gordo Rio Zape Bean
Rio Zape is similar to a classic Pinto bean, but it's denser and exudes a deep, rich pot liquor. They don't work well in a lot of recipes, because they are so rich and distinct. In Mexico, there's a great dish called enfrijoladas that uses pureed black beans as the basis for a sauce, similar to enchiladas but with beans instead of chile sauce. We've made this dish with Rio Zape beans and they seem born for the dish. They also make excellent refried beans.
