4. Cut corn tortillas in small strips. Fry in hot oil until crisp. Drain well.
5. Remove seeds from pasilla pepper and cut in strips. Soak pepper strips in 1/4 cup hot water for 5 minutes. Drain and pat dry.
6. To serve soup, place few strips of tortillas and pasilla peppers in each bowl. Pour soup over them. Sprinkle soup with grated cheese and few strips of peppers. Serve at once.
BLACK BEAN SOUP: Proceed as above Steps 1 to 3 using Black beans instead. For a coarse cream use a food mill instead of blender. Serve with a dollop of sour cream.
NOTE: 1) Dry beans may be cooked faster in a pressure Cooker, for pinto beans about 1 hour after reaching pressure.
2) For a variation, simmer soup longer until it thickens slightly. Omit fry tortillas, increase pasilla peppers strips.
