You will find that refried beans are one of the most common sides for traditional mexican dishes. From breakfast, to dinner, they are always a welcome companion. You can make them with different kinds of beans, like black, pinto, or peruvian. The choice in mexico varies among regions but also among cooks. I tend to use the pintos more, because they have a creamier consistency and softer flavor. The black, delicious as well, have a stronger flavor and texture.
