Slow Cooker Pork Tacos

2 cups store-bought salsa, plus more for serving

2 tablespoons chili powder

2 tablespoons dried oregano

2 tablespoons unsweetened cocoa powder

kosher salt

1 2 1/2-pound boneless pork butt or shoulder, trimmed of excess fat

18 corn tortillas

1/2 cup fresh cilantro sprigs

3/4 cup sour cream

1 lime, cut into wedges

In a 4- to 6-quart slow cooker, combine the salsa, chili powder, oregano, cocoa, and 1 teaspoon salt. Add the pork and turn to coat.
Cook, covered, until the meat is tender and pulls apart easily, on high for 4 to 5 hours or on low for 7 to 8 hours. Twenty minutes before serving, heat oven to 350° F. Stack the tortillas, wrap them in foil, and bake until warm, about 15 minutes. Meanwhile, using 2 forks, shred the pork and stir into the cooking liquid. Serve with the tortillas, cilantro, sour cream, lime, and extra salsa.
