Mole sauce is a mexican condiment primarily composed of fruit, chile pepper, nuts and spices. In our rendition, these ingredients take the form of raisins and tomatoes; ancho chiles; smoked almonds; and cocoa, cumin and cinnamon. The rich mixture coats the browned chicken thighs in the slow cooker, and doubles as a topping on the final dish. Garnish with fresh cilantro leaves, if desired.
