PORK EMPANADAS WITH THYME

Steps:

• Set a steamer basket in a pot with 2 inches boiling water. Add potato, cover, and cook until tender, 10 to 15 minutes. In a large skillet, heat oil over medium. Add onion and garlic; cook, stirring occasionally, until onion softens, 5 to 7 minutes. Raise heat to high and add pork, thyme, and sage; cook, breaking up meat with a spoon, until pork is no longer pink, about 4 minutes. Add flour; cook, stirring, until blended, about 30 seconds. Add raisins (if using) and 2 tablespoons water; cook until thickened, about 1 minute. Remove from heat and stir in potato, pine nuts (if using), and vinegar. Season filling with salt and pepper and let cool.
• Preheat oven to 400, with racks in upper and lower thirds. On a floured surface, divide dough in half and roll each piece to an 1/8-inch thickness. Using a 6-inch cookie cutter or plate as a guide, cut out 8 circles. Place 1/4 cup filling on half of each circle, leaving a 1/2-inch border. Brush edge of dough with water; fold top half over filling. Press edges to seal, then crimp firmly with a fork.
• Transfer empanadas to two baking sheets lined with parchment. In a bowl, beat egg with 1 tablespoon water. Brush empanadas with egg wash and top with thyme sprigs. Bake until golden brown, 30 to 40 minutes, rotating sheets halfway through.
