Empada de Peixe à Maniera de Macao

Ingredients
FOR THE MACANESE PASTRY DOUGH: FOR THE PIE:
 * 2 1/4 cups flour
 * 1/4 cup sugar
 * 1/2 tsp. baking powder
 * Pinch salt
 * 4 tbsp. cold butter, cut into pieces
 * 8 tbsp. cold margarine, cut into pieces
 * 1 egg
 * 1 egg yolk
 * 1 tbsp. port
 * 1 lb. red snapper filets
 * Salt and freshly ground black pepper
 * Flour
 * 2 tbsp. olive oil
 * 1 clove garlic, crushed and peeled
 * 2 scallions, trimmed and chopped
 * 1 1/2 tsp. ground cumin
 * 1 1/2 tsp. ground coriander
 * 3/4 tsp. ground turmeric
 * 1 recipe Macanese pastry dough
 * 3 sprigs fresh mint, chopped
 * 1/4 cup green olives
 * 2 tbsp. freshly grated parmigiano-reggiano

Directions
1. For the Macanese pastry dough: Sift together flour, sugar, baking powder, and salt in a medium mixing bowl. Using a pastry cutter or 2 knives, work butter and margarine into flour until it resembles coarse meal. Make a well in the center, and add egg, egg yolk, and port; then beat together with a fork until frothy. Gradually work in flour until mixture just holds together. Knead dough a few times on a lightly floured surface using the heel of your hand and pressing down and away from you to make a smooth, dense dough.

2. Divide dough in half and shape into rounds. Roll out rounds on a lightly floured surface into 8'' circles (dough rounds will be fragile).

3. For the pie: Run your fingers over the fish filets, then remove any bones that you feel. Generously season fish with salt and pepper, then lightly dredge in flour. Heat 1 tbsp. of the oil in a large skillet over medium heat and fry fish on both sides, about 1 minute per side. Remove fish from skillet and set aside. Heat remaining 1 tbsp. oil in the same pan. Add garlic and half the scallions and cook until soft and fragrant, about 1 minute. Add cumin, coriander, and turmeric and cook for 30 seconds. Add 1/2 cup water and return fish to skillet. Season to taste with salt and pepper and simmer until fish is just cooked through, about 4 minutes. Allow fish to cool, then use a fork to break fish into large chunks.

4. Preheat oven to 350°. Fit 1 pastry round into an 8'' pie pan and, with your fingertips, press dough to fit pan. Spoon filling into pie shell, then sprinkle with remaining scallions and the mint. Scatter olives on top, then sprinkle with parmigiano-reggiano. Cover pie with remaining pastry round, crimp edges, and cut a few slits in the center for steam to escape. Bake until crust is golden and filling is hot, about 35 minutes.
