Prepare the Chilies:Remove the stems and seeds from the dried ancho, guajillo, and pasilla chilies. Toast them lightly in a dry pan over medium heat for 2-3 minutes to release their aroma. Set aside.
Toast the Seeds and Nuts:In the same pan, toast sesame seeds, pumpkin seeds, and almonds for 3-4 minutes, stirring constantly to avoid burning. Set them aside once toasted.
Cook the Vegetables:Heat olive oil in a medium skillet over medium heat. Add the chopped onion and garlic and sauté until fragrant and soft, about 5 minutes. Add the diced tomatoes and cook for another 2 minutes until the tomatoes soften.
Blend the Mole Sauce:In a blender, combine the toasted chilies, sesame seeds, pumpkin seeds, almonds, onion, garlic, and tomatoes. Add cinnamon, cumin, cloves, cocoa powder, brown sugar, and chicken broth. Blend until smooth. Add more broth if necessary to reach the desired consistency.
Simmer the Sauce:Transfer the blended sauce to a saucepan. Cook over low heat, stirring occasionally, for 20-30 minutes to allow the flavors to meld. Add salt to taste.
Serve:Once the sauce thickens and becomes aromatic, your Mole Sauce is ready to serve! Drizzle over roasted chicken, tacos, enchiladas, or any of your favorite dishes.
