Cream butter with 1/2 cup of sugar. Add egg yolk, salt, and flour sifted before measuring. Mix together. Pat dough in thin layer in an ungreased 10 x 15 inch pan. Beat egg whites until stiff, gradually adding the cup of sugar. Beat until a meringue consistency is produced. Fold in walnuts and lemon flavoring.
