Cream the softened butter with orange rind; add the 
     sugar gradually, beating until fluffy.  Add egg and 
     orange juice and beat well.  Add the dry ingredients 
     together, to make a soft dough that can be handled. 
     Chill before rolling out.  Roll out on lightly floured 
     board to 1/8 inch thickness. Cut into 3-inch circles 
     with cookie or biscuit cutter.  Place 1/2 Tbsp. filling 
     (prune lekvar, poppy seed filling, or jam) in center of
     each round.  Brush edge with water if desired.  Fold 
     three sides in towards center, pinching to form 
     three-sided cookie.  Bake on ungreased cookie sheets
     at 350 degrees for 9-10 minutes, until cookie begins to
     brown. 

     Makes 4-5 dozen.
