I am not sure where we found this recipe, but it is one of our top favorites. The tamales do take a good afternoon to prepare, but there is often extra to share or to freeze.
Look for the corn husks at a Mexican store if there is one near you. Soak the dried beans over night before cooking, or see notes to use canned beans. Be sure to soak the corn husks a few hours ahead of time. Homemade tomatillo sauce is recommended.
