Preparation / Directions:
Arrange chilies on a large baking sheet and bake in a 350F oven until chilies smell toasted (about 10 minutes). Discard stems and seeds; grind chilies to a powder in a blender (or substitute 1/4 cup ground chile powder for roasted, ground chilies.)
To blender, add almonds, banana, cinnamon, garlic, tortillas, sesame seeds, pine nuts and 1 cup of the chicken broth. Whirl until pureed. (Sauce will be grainy.)
Pour into a pan; add butter or margarine, chocolate, and remaining chicken broth. Heat to a simmer, stirring. Season to taste with salt if necessary.
