1 cup sugar
2 cups sifted flour
1 1/2 tablespoons ground cinnamon
1 teaspoon salt
1 1/2 cups chopped walnuts

Place walnuts in a small bag.

Preheat the oven to 325 degrees.  Grease and flour a cookie sheet baking pan.  Beat together 1 cup butter and 1 egg yolk.  Add the cookie mix to the butter/egg mixture and mix well.  Press the batter into the prepared pan.  Beat the egg white until foamy and spread sparingly over the top of the batter.  Sprinkle the walnuts on top, pressing down firmly.  Bake for 30 minutes.
