Rub

1. Lightly score the lamb meat with a knife, and pat dry with paper towels. 
2. Season the lamb generously with salt and pepper; place on a wire rack set inside a rimmed baking sheet. 
3. Grind the cumin, caraway, and coriander seeds with a mortar and pestle to a powder. 
4. Transfer to a small bowl, and stir in the chiles, garlic, oil, paprika, and cinnamon; rub all over the lamb. 
5. Chill, uncovered on the wire rack, for 12 to 24 hours. 

Assembly

1. Let the lamb come to room temperature, about 1 hour. 
2. Preheat the oven to 450°F. 
3. Roast the lamb until well browned all over, about 20 to 25 minutes. 
4. Remove from the oven, and reduce the temperature to 250°F. 
5. Meanwhile, grind the caraway and coriander seeds with a mortar and pestle to a powder. 
6. Heat the oil in a large Dutch oven over medium. 
7. Add the onion, and cook, stirring occasionally, until translucent, 5 to 7 minutes. 
8. Add the ancho and chipotle chile powders, turmeric, pepper, cinnamon, and ground seeds; stir to coat the onion. 
9. Cook, stirring, until the spices are fragrant, about 2 minutes. 
10. Add the tomatoes and broth, and bring the liquid to a simmer; season lightly with salt. 
11. Carefully place the lamb in the pot, and add just enough water to cover, if it is not submerged. 
12. Cover the pot, and braise the lamb in the oven until the meat is very tender and the bone wiggles easily in the joint, 4 ½ to 5 ½ hours. 
13. Cool to room temperature and then refrigerate overnight.
14. Heat over medium-low to a simmer.
15. Transfer the lamb to a platter and tent with foil to keep warm while you make the sauce and salad. 
16. Increase the heat to medium-high, and bring the braising liquid to a boil; cook, stirring often to prevent sticking, until reduced by one-half, 25 to 30 minutes. 
17. Taste the sauce and season with salt, if needed; spoon over the lamb. 

Salad

1. Place the onion in a small heatproof bowl. 
2. Bring the vinegar and sugar to a boil in a small saucepan, stirring to dissolve the sugar. 
3. Pour over the onion, and let cool. 
4. Drain the onion, and place in a medium bowl; add the lemon, cilantro, mint, parsley, and dill; toss to combine. 
5. Drizzle lightly with oil, season with salt, and toss again to coat.
