<p>In bowl of blender, puree corn and ½ cup water until smooth; set aside.</p>

<p>In large non-metallic bowl or container, mix together Naranja Agria, lemon juice, Adobo, Sazón, pepper and cumin until combined. Add pork pieces and stir until coated in marinade; let marinate 10 minutes at room temperature. Drain pork, reserving marinade.</p>

<p>Heat oil in medium, heavy pot over medium-high heat. Add pork in batches, taking care not to crowd pot; cook, flipping occasionally, until well browned on all sides, about 7 minutes per batch. Transfer pork to plate. Add onions, pepper and garlic to same pot. Cook, stirring occasionally, until vegetables are soft and translucent, about 5 minutes. Stir in tomato sauce, wine, reserved marinade and remaining water; bring to boil. Using whisk, slowly whisk in cornmeal; stir in reserved corn puree and reserved pork. Return water to boil. Reduce heat to medium-low; cover pot. Simmer, covered, stirring occasionally, until cornmeal thickens and pork is tender and cooked through, about 1 hour.</p>

<p>To serve, ladle tamal casserole into bowls. Garnish with cilantro, if desired.</p>
