A massive ceremonial tamal filled with chicken and pork, cooked underground for Day of the Dead. This chicken and protein-rich dish is a sacred family tradition of Yucatecan cuisine.
Preheat oven to 350°F if not cooking underground, or prepare your fire pit by heating stones for several hours.
Rub chicken and pork with achiote paste, salt, black pepper, and minced garlic; marinate for 30 minutes.
Sear chicken and pork in a large pot on medium-high heat until well browned, then add orange juice and 2 cups chicken stock. Simmer covered for 45 minutes.
Mix masa harina, baking powder, salt, and lard in a large bowl. Gradually add remaining chicken stock, kneading until dough is smooth and moist.
Briefly pass banana leaves over an open flame to soften; line a roasting pan or pit with leaves, overlapping to fully cover.
Spread half of the masa mixture over the leaves, layer cooked chicken and pork in the center, then top with the rest of the masa. Fold leaves over to enclose.
Cover tightly and bake for 3 hours in oven, or place in fire pit, cover with earth and hot stones, and cook for about 4 hours. Rest for 30 minutes before uncovering.
Carefully unwrap banana leaves and slice tamal into portions. Serve warm.
