Preheat oven to 375. In large bowl, mix together strawberries, powdered sugar and cornstarch. Set aside for later use. Working on well floured surface, roll out dough to a thickness of about 1/8 inch. Using a 4 inch ring or large cookie cutter, cut out six circles of dough. Cut out another six 3 inch diameter circles. You should have twelve dough circles, six one inch large than the others. Put the six larger dough circles into pans, using your fingers to gently press dough into bottom and up sides. Pour strawberry mixture evenly into each pan. Cut 1 inch hole in center of six smaller dough circles. Put the six smaller circles on top of strawberry mixture and gently crimp together top and bottom layers of dough so pie is sealed all the way around. Mix beaten egg and milk together in small bowl. Brush each top layer of dough with egg mixture and sprinkle on sugar evenly. Refrigerate for 15 minutes. Bake for 30 minutes or til top of pie turns golden brown. Transfer pans to wire rack and let cool for 30 minutes Serve tarts or store in sealed container at room temperature for up to 2 days.
