In a small bowl mix together all ingredients except pork. Add the pork to a large bowl, pour in the marinade mixture and mix together until the pork is well coated.
For the dough:
Preheat oven to 400 degrees F.
In a large bowl, mix together flour, cornmeal, baking powder, salt, and sugar and cut in butter until the mixture is crumbly. In a small bowl, lightly beat the eggs and mix in the water, lemon juice, milk, lemon peel and corn. Add the wet mixture to the dry mixture and combine to form a soft and pliable dough. Knead the dough until fully mixed. On a floured surface, roll the dough out to 1/4-inch thickness and cut into 5-inch rounds.
Fill each round with 1 to 2 tablespoons of meat filling. Fold the dough in half and dab the edges with water to seal. There should be a 1/2-inch of dough to work with to form the seal. For a tight seal, press with the tines of a fork all around the edge of the empanada. Transfer the empanadas to a lightly buttered baking sheet and bake for 10 to 15 minutes.
Arrange the empanadas on a serving platter.
For the chimichurri:
In a small saute pan over medium-low heat, add 2 tablespoons of oil. Add the apples, lemon juice, parsley, onions and apple cider vinegar and saute until onions and apples become soft, about 3 minutes.
In a serving bowl, add 6 tablespoon olive oil. Add the sauted apple mixture to the bowl and stir to combine. Season with salt and pepper, to taste, and serve on top of the empanadas.
