1 whole fresh chicken
5 black peppercorns
Kosher salt
1/2 cup sesame seeds
¼ teaspoon ground cloves
½ teaspoon cinnamon
1/2 teaspoon anise seeds
1/4 teaspoon coriander
6 dried guajillo chile peppers
4 dried ancho chile peppers
6 tablespoons canola oil
1/4 cup raisins
1/4 cup whole blanched almonds
1/4 cup hulled pumpkin seeds
2 6 -inch corn tortillas
75 grams dark chocolate
1 teaspoon sugar
Salt to taste
Put the chicken and peppercorns in a large pot, cover with water and season with salt. Bring to a gentle simmer over low heat and cook done, about 40 minutes. Transfer the chicken to a plate and set the cooking liquid aside.
Toast the sesame seeds in a dry skillet over medium heat, until golden, about 5 minutes. Set aside 2 tablespoons for garnish and transfer the rest to a blender. In the same skillet, toast the cloves, cinnamon, and anise and coriander until fragrant, about 2 minutes. Add to the blender.
Remove the stems and seeds from the dried chili peppers. Heat 4 tablespoons canola oil in the same skillet over medium heat. Add the chiles and fry until lightly toasted, about 2 minutes. Transfer to a bowl, cover with hot water and set aside to soak until pliable, about 30 minutes.
Meanwhile, add the raisins, almonds, pumpkin seeds and tortilla pieces to the oil in the skillet and cook, stirring, until the seeds and tortillas are golden brown, about 2 minutes. Add to the blender along with the oil from the skillet.
Add the softened chiles and puree, pouring in 2 to 3 cups of the soaking liquid to make a thick, smooth sauce.
Heat 2 tablespoons oil in a large pot over medium-high heat. Add the chile sauce and fry, stirring, until thickened, 5 to 6 minutes. Add 2 cups of the reserved chicken cooking liquid and simmer until the sauce starts to thicken, about 20 minutes.
Add the chocolate, sugar and salt and simmer, stirring frequently, until the chocolate melts and the sauce reduces, about 20 more minutes.
Add the chicken pieces to the sauce and warm through over low heat. Garnish with the reserved sesame seeds.
