Step 1: Preheat oven to 300 degrees. Grease a large, covered baking dish.
Step 2: Place pork in baking dish.
Step 3: Place damp chiles in a layer on baking sheet and toast them in oven for about five minutes, until they darken just a shade. Watch chiles carefully because they can scorch quickly. Leave oven on.
Step 4: Cool chiles briefly, then break each into two or three pieces, and discard stems and most seeds.
Step 5: Place approximately half of chiles into a blender with one cup of stock or water. Purée until you have a smooth, thick liquid.
Step 6: Pour mixture into baking dish.
Step 7: Repeat with remaining pods and stock.
Step 8: Pour mixture into baking dish and stir sauce together with pork.
Step 9: Cover dish and bake at 300 degrees until pork is quite tender and sauce has cooked down, about three hours.
Step 10: If sauce seems watery, return dish to oven uncovered and bake for an additional 15 minutes, or as needed.
