Arepas with Pulled Pork and Pickled Onion Recipe

Directions:

1. Make pickled onion: Stir together all pickled onion ingredients in a bowl and chill, covered, at least 12 hours.
2. Marinate pork while onion chills: Toast cumin, allspice, and peppercorns together in a dry heavy skillet over moderate heat, stirring, until fragrant, 1 to 2 minutes. Finely grind toasted spices with achiote in an electric coffee/spice grinder or with a mortar and pestle. Mince garlic and mash to a paste with salt using a heavy knife, then transfer to a 2 1/2- to 3-quart shallow glass or ceramic baking dish. Stir in spice mixture, oregano, orange juice, and vinegar. Add pork and rub meat all over with marinade. Marinate pork, covered and chilled, at least 2 hours.
3. Cook pork while onion chills: Preheat oven to 325°F.
4. Bring pork to room temperature, then add water to baking dish and cover tightly with foil. Bake in middle of oven until very tender, 1 3/4 to 2 hours. (Leave oven on.)
5. Uncover pork and, when cool enough to handle, shred meat on a cutting board, discarding bones and excess fat. Transfer meat and any juices accumulated on cutting board to baking dish.
6. Make arepas while pork cooks: Bring milk to a simmer in a small saucepan, then remove from heat and reserve 1/2 cup in a small bowl. Add butter to remaining 2 1/2 cups hot milk and stir until melted.
7. Toss together arepa flour, sugar, salt, and mozzarella in a large bowl. Add hot milk with butter and stir until combined. Let mixture stand until milk is absorbed, 1 to 2 minutes (dough will be soft; it will continue to stiffen as it stands).
8. Form 1 level tablespoon dough into a ball. Flatten ball to a 1 1/2- to 1 3/4-inch-diameter disk and transfer to a wax-paper-lined tray. Form more disks with remaining dough in same manner, stirring in some of reserved milk if dough becomes too stiff and edges of disks crack when flattened.
9. Heat 1/2 tablespoon oil in a 12-inch nonstick skillet over moderately low heat until hot, then cook arepas in batches of 10 to 12, turning over once, until golden in patches, 8 to 12 minutes total. (Add more oil to skillet between batches as needed.) Transfer to baking sheets as cooked.
10. Reheat arepas in batches as needed, covered with foil, until heated through, 10 to 15 minutes, then top with pork and pickled onion. Serve warm.
11. Cooks' notes: ·Pickled onion can be made 2 days ahead and chilled, covered. ·Pulled pork can be made 2 days ahead, first marinated (up to 1 day), then cooked and shredded 1 day ahead and chilled, covered. Reheat, covered, in a 350°F oven 10 to 15 minutes. ·Arepas can be made 1 day ahead and cooled completely, then chilled, covered. Reheat in oven before serving. Arepas can also be made 2 weeks ahead and frozen, layered between sheets of plastic wrap, in an airtight container. Thaw 30 minutes at room temperature before reheating.
