Preheat the
oven to 325F. Blend the confectioner's sugar into the butter, and then
gradually add the flour, 1 cup at a time. Dough will be very thick.
Place dough on floured surface, pat down, roll out 1/4 to 1/2 inch
thick. Cut into 2 1/2 inch squares, and place on an ungreased baking
sheet. Prick the top of each square with a fork. Bake at 325F for 25-30
minutes; cookies should be pale on top, but golden brown on the bottom.
Remove from oven and cool on wire racks. Store in an airtight container.
Scotland's
favorite, this cookie requires the very best fresh butter for its
flavor.
