Mexican mole sauce can be intimidating. There’s chocolate, chiles, and spices. It’s rich, full of flavor, and not too sweet, despite the chocolate. And it’s typically a labor-intensive process. But this recipe, based on Martha Stewart’s, takes little effort, thanks to the slow cooker. With an entire can of chipotle chiles in adobo sauce, along with ancho chiles and almonds, this mole is nicely spicy without being overbearing. Prep is a breeze: Just blend everything up, put it in the slow cooker with some chicken, and forget about it for 4 to 8 hours. The recipe yields lots of extra sauce, so put some out with tortilla chips before serving it for dinner.
