1. Preheat oven to 350°. Heat 2 tbsp. oil in a large, heavy-bottomed, ovenproof pot over medium-high heat. Add onions and garlic and cook, stirring, until onions are golden, about 6 minutes. Remove from heat and transfer onions and garlic to a bowl with a slotted spoon.
2. In a large bowl, stir together flour, salt, cumin, and pepper. Add pork and toss to coat. Return pot to medium-high heat, add remaining 1 tbsp. oil, and, working in batches, lightly brown meat on all sides, 5 to 7 minutes per batch. Transfer meat to a separate bowl as you go.
3. Return onions and garlic to pot. Sprinkle with ground chiles and cook, stirring, 2 minutes (mixture will be thick). Add broth, stirring to loosen browned bits from bottom of pot. Whirl sauce in a blender until smooth. Return sauce to pot and add bay leaf and reserved pork.
4. Cover pot, put in oven, and cook 1 hour. Set lid slightly ajar and cook until pork is fork-tender, about 1 hour more. Remove bay leaf before serving.

Cooking with chiles
Ground dried red chiles are used to both season and thicken sauces (don't be intimidated by the large quantities called for; this ingredient is nothing like cayenne or supermarket âÂ€Âœchili powder,âÂ€Â� which is a blend of several seasonings). The ground chiles are sold according to heat level (from mild and sweet to quite spicy), so be sure to buy a batch that suits your taste. Look for it in Latin markets and gourmet stores, or see âÂ€ÂœFinding New Mexico Chiles,âÂ€Â� (below) for mail-order sources.
