Directions

1. Cut slit in 1 long side of each chile; pull open.
2. Remove seeds and membranes; press chiles flat.
3. Cut pasilla chiles into 1x1/4-inch strips.
4. Cut 6 tortillas into 1x1/4-inch strips.
5. Heat 2/3 cup oil in heavy medium skillet over medium-high heat until very hot. Working in batches, add tortilla strips to skillet; toss until crisp and golden, about 1 minute. Using slotted spoon, transfer strips to paper towels. One at a time, fry 6 whole tortillas in oil until golden and almost crisp, about 30 seconds per side.

8. Add pasilla chile strips to skillet; stir 10 seconds.
9. Transfer to paper towels to drain.
10. Combine tomatoes and next 5 ingredients in heavy large pot. Coarsely crumble whole tortillas, then guajillo chiles into pot. Bring to boil. Reduce heat to medium; cover and simmer until water is almost absorbed and chiles are soft, stirring occasionally, about 6 minutes. Working in 3 batches, puree mixture in blender until smooth, adding 1/4 cup broth to each batch.
11. Heat 2 tablespoons oil in large saucepan over medium-high heat.
12. Add tomato mixture; stir until thick and deeper in color, about 2 minutes.
13. Add 3 1/4 cups broth; bring to boil. Simmer 8 minutes to develop flavors. Season with salt.
