Six chilies are combined with Mexican hot chocolate for a smoky and spicy sauce that can coat any or all of your favorite Mexican dishes.
Preheat oven to 350°F. Remove stems and seeds from all chile peppers. Place peppers on shallow-rimmed baking sheet; toast in 350°F oven 3 minutes. Remove from oven; set aside to cool.
Heat oil in medium saucepan over medium heat. Add onion and garlic; cook 3 to 4 minutes, stirring occasionally. Add chiles, beef stock, pumpkin seeds and paprika; bring to a boil. Reduce heat to low; stir in chocolate until chocolate is melted. Cover and simmer 25 minutes, stirring occasionally. Remove from heat; cool 10 minutes.
Place chile mixture into blender container; add salt and black pepper. Cover; pulse on and off until smooth. Strain sauce through fine mesh strainer.
