My wonderful friend is from Mexico, and in liew of payment for wonderful services, she made my family a big pot of Posole. I have yet to pin her down on the exact ingredients,esposote, some tomato, garlic etc,but she mentioned to me that she uses pork neck to give the soup that unctious flavor. Bones and all. My excurisions online have led me to Posole with chicken breasts, with sausage or pork loin. What's the real deal???
