This is an easy and delicious pork stew. Posole is the Spanish word for hominy (lime-treated whole corn kernels). You can used drained, canned hominy and it's good and easy to find, but a stronger flavor comes from fresh or frozen posole. There is red posole (red chilies) and white posole (green chilies), and both are popular throughout Mexico, New Mexico and parts of the southwest. Posole probably originated with the Pueblo Indians, and has become a real must for Christmas Eve, New Year's eve or New Year's day to bring good luck. But most people enjoy this stew year-'round as well, especially in winter.
