Step 2
Mix the masa harina with water in a small bowl, and let stand until the corn flour has absorbed the water and made a pliable dough, about 10 minutes. Form the masa dough into a 2 inch ball. Place the dough ball, tomatoes, tomatillos, garlic, onion, guajillo peppers, cinnamon stick, cumin seeds, cloves, peppercorns, epazote, and achiote seed into the broth, bring to a boil, reduce the heat, and simmer until the vegetables are tender, about 20 minutes.
