Cook the meat with the crushed garlic head and let it fry in its drippings. Cook, separately the zucchini and string beans. Toast the chiles guajillo, remove the veins and soak them, then grind them with both the crushed tomatillos and 4 garlic cloves. Add a little beef broth, fry strongly and add the cooked meat and a little broth. Thicken with corn flower. Make some dough with the corn masa and make little balls and perforate them with the finger. Add them to the stew, when it is boiling, as well as the zucchini and green beans, separately cooked.
