BLUEBERRY AND MASCARPONE TURNOVERS

Steps:

• In a small bowl, mix together the mascarpone cheese, sugar, cornstarch, lemon zest, and lemon juice until smooth. Stir in the blueberries.
• Using the cookie cutter, cut the pie crusts into 12 circles. Place the dough circles on a parchment paper-lined baking sheet. Using a pastry brush, lightly brush the edges of each piece of dough with the egg. Spoon about 1 1/2 teaspoons of the cheese mixture in the center of each circle. Fold the dough in half to enclose the filling and pinch the edges to seal. Using the tines of a fork, gently crimp the sealed edges. Refrigerate for 10 minutes.
• In a large, heavy-bottomed saucepan, pour enough oil to fill the pan about a third of the way. Heat over medium heat until a deep-frying thermometer inserted in the oil reaches 375°F. (If you don't have a thermometer, toss in a cube of bread; it will brown in about 3 minutes and, when it does, the oil is ready.) Fry the turnovers, turning once, for 1 to 1 1/2 minutes, until golden.
• Drain on paper towels and sprinkle with sugar while still hot. Cool for at least 10 minutes before serving.
