Directions

1. 1
   In a bowl, using a wooden spoon or your hands, or in an electric mixer, combine the butter and cream cheese; stir in the salt.
2. 2
   Gradually add the flour, making a sticky dough.
3. 3
   Sprinkle the outside of the dough with flour, wrap in plastic, and refrigerate for at least 1 hour and up to 24 hours.
4. 4
   Preheat the oven to 350F.
5. 5
   Working with about a quarter of the dough at a time, roll it out to less than 1/4-inch thickness (3/16 is about right), using flour as necessary to prevent sticking.
6. 6
   Cut into 2-inch squares and put a dollop of one of the preserves in the center of each square or spread it across the diagonal, stopping short of the edges.
7. 7
   Roll up and seal, or fold into triangles, or, if you spread the filling on the diagonal, bring up the corners and pinch across the center.
8. 8
   Brush each finished cookie with egg white and sprinkle with sugar, then put on a greased or nonstick cookie sheet and bake for 10 to 15 minutes, or until very lightly browned.
9. 9
   Cool and serve within a day.
