There are many versions of pozole, depending on the region- but most commonly you'll see Pozole Rojo (Red Pozole) made with red guajillo chiles, ancho chilies, or other dried chilies- or Pozole Verde, made with green ingredients like tomatillos, poblano peppers, serrano peppers, and cilantro. Regional spices and ingredients influence other variations as well. One of Pozole's main components, no matter what the color, is hominy!
