Step 1

Sift together the flour, baking powder, and salt. Set aside.

Step 2

In a separate bowl, beat the butter, then add the sugar a little at a time. Add the vanilla. Beat the mixture until it is nice and fluffy. Beat in the egg. Stir in the flour mixture alternately with the milk.

Step 3

Before you use this dough, be sure you chill it well at least 2 hours or even overnight.

Step 4

To make turnovers: Preheat the oven to 350 degrees F (175 degrees C). Roll dough out to 1/4 inch thickness on a lightly floured surface. Cut into 3 inch squares. Spoon about 2 teaspoons of the pie filling into the center of each square and fold over to form a triangle. Pinch the seams to seal or press with the tines of a fork. Place at least 2 inches apart on a greased baking sheet. Brush with egg white.

Step 5

Bake for 12 to 15 minutes in the preheated oven, until golden brown on the tops and bottom.
