1Empanada Dough: In a mixing bowl combine the masa harina, flour, cornmeal and baking powder. Season with the salt and pepper and mix thoroughly. Cream in the lard and add the water a little at a time, working the mixture until all is completely incorporated. Using your hands, form the dough into a log about 12 inches long by 3 inches across and refrigerate for about 20 minutes.
2In a large saute pan, over medium heat, add the oil. When the oil is hot, add the onions. Season with salt and crushed red pepper. Saute for 2 minutes. Add the chicken. Saute for 2 to 3 minutes. Remove from the heat and turn into a mixing bowl. Add the garlic, green onions, olives, and raisins. Season with salt. Mix well.
3On a floured surface, roll the dough out to a circle, 1/8-inch thick. Using a 4-inch round cutter, cut the dough into individual circles. Press the remaining dough together and repeat the above process. Preheat the fryer. Place about 1 tablespoon of the filling in the center of each circle. Lightly wet the edges of the dough with water. Fold the dough over, forming a half-moon, using your fingers, seal the edges completely and crimp the sides of the dough. Place the finished empanadas on a parchment lined baking sheet.
4Fry in batches until golden brown, about 2 to 3 minutes. Remove and drain on paper towels. Season with salt. Serve warm on a large platter. Garnish with parsley.
