01 - Preheat the oven to 325°F (165°C). Line a baking sheet with parchment paper or foil.
02 - Pat pork belly cubes dry with paper towels. Season evenly with kosher salt, black pepper, and smoked paprika.
03 - Arrange seasoned pork belly cubes on the prepared baking sheet, spacing them apart. Bake for 60 minutes, turning cubes once halfway through, until they are tender and the fat is rendered.
04 - While pork is baking, combine pomegranate juice, honey, soy sauce (or tamari), apple cider vinegar, minced garlic, and ground cumin in a small saucepan over medium heat. Simmer, stirring occasionally, until the mixture reduces to a thick syrup, about 15 to 20 minutes. Remove from heat and set aside.
05 - Once pork is cooked, remove from the oven. Increase oven temperature to 425°F (220°C). Brush the pork belly cubes generously on all sides with the pomegranate glaze. Roast for 10 to 15 minutes, or until caramelized and glossy.
06 - Transfer glazed pork belly bites to a serving platter. Drizzle with any remaining glaze. Garnish with fresh pomegranate seeds, chopped cilantro or parsley, and toasted sesame seeds if using. Serve warm.
