8. Step 8

   Divide and shape the dough into 2 logs. Wrap each in waxed paper and refrigerate at least 8 hours or overnight. 

9. Step 9

   When ready to bake, remove the waxed paper and brush the logs with the beaten egg white. Roll the logs in the demerara sugar or sanding sugar. Gently press the sugar into the log to make sure it sticks.
