Preheat the oven to 450˚F. Unroll pie crusts on a silicon mat and cut out large circles using a scalloped cookie cutter or even a small bowl. My cookie cutter was 5 inches wide. I had to knead and re-roll the scraps to get 6 out of each crust.
Put the crusts in greased muffin tins, leaving an empty space between crusts. Press them into the bottom and on the sides. Ruffle and then flatten the tops so they lay flat. Prick the bottoms with a fork.
Brush lightly with beaten egg white and sprinkle with sugar.
Bake at 450 degrees for 8-10 minutes.
