Yucatán's charred chile sauce stew, made by burning dried chiles to create a distinctively smoky flavor. This protein-rich, family dish delivers bold, unique flavors found nowhere else in Mexico.
Burn the dried ancho, pasilla, and guajillo chiles directly over a gas flame or a hot dry skillet, turning with tongs, until blackened but not fully disintegrated, about 1-2 minutes per side. Set aside to cool.
Place the chicken thighs in a large pot with 8 cups of water, bring to a boil, and simmer on low heat for 30 minutes. Skim off and discard any foam that rises.
Meanwhile, toast the corn tortillas in a dry pan until dark brown but not burnt, about 2 minutes per side. Char the onion and tomato under the broiler or over an open flame until the skins are well blistered.
In a blender, combine scorched chiles (seeds and stems removed), toasted tortillas, charred onion and tomato, garlic, black peppercorns, allspice, oregano, cumin, lard or oil, and about 1.5 cups of the chicken broth. Blend until you have a deep, smooth paste.
Pour the chile paste into the simmering chicken. Stir well, add salt, and cook uncovered on low heat for 1 hour, stirring occasionally to prevent sticking and to allow flavors to meld.
Before serving, peel and halve the hard-boiled eggs. Add to the stew and simmer gently for 5 minutes more. Taste and adjust seasoning before serving hot.
