Lone Star Style Pulled Pork Tacos

Preheat the oven to 300 degrees. Place a large sheet of heavy-duty aluminum foil in a large baking dish. Mix the chili powder, cumin, salt and pepper in a small bowl. Place the pork in the center of the foil and season with the spice mixture. Whisk together the jam, brown sugar, orange juice and garlic in a small saucepan over medium heat. Cook, stirring frequently, until the brown sugar is melted and the sauce is slightly thickened. Spoon the mixture over the pork, turning to coat. Add the jalapeños and onions, and tightly wrap the pork with the foil. Roast for about 4 hours until fork tender. After the pork has cooled slightly, unwrap and transfer to a plate, reserving jalapeños and onions. Discard the juices and foil. Use a fork to shred the pork, discarding any fat. Toss in the jalapeños and onions, and transfer to a serving platter. Serve with tortillas, cilantro, avocados and lime wedges.
