"This Mexican take on stuffed peppers features a creamy, cheesy, tomato-based filling and an enchilada-style sauce. [Photograph: Jennifer Olvera] These Mexican-flavored peppers sport a cheesy, creamy beef-and-rice filling that's spiked with chili powder and cumin. It's topped with an enchilada-style sauce and gets its depth from ancho chili and unsweetened cocoa powders and its aromatics from cumin and lightly floral Mexican oregano. Why this recipe works: * The creamy, moist filling incorporates sour cream, cheese, and crushed tomatoes. * Using two cheeses, American and cheddar, keeps the texture lush and the flavor rich. * A chile, cumin, and unsweetened cocoa-infused, enchilada-style red sauce ties everything together. Note: The filling can be prepared in advance, and the peppers may be stuffed ahead of time. The same is true of the sauce; however, store the two components separately in the refrigerator. Remove the peppers and sauce from the refrigerator about 45 minutes before cooking to bring them to room temperature...."
