To makes the cinnamon syrup, combine water, sugar and cinnamon bark chips in a medium pan and bring to a boil for 5 minutes. Let cool overnight and strain remaining cinnamon chips with a chinois or other fienmesh strainer, so you are left with just the syrup.
To make the cocktail, combine all ingredients in a shaker tin and give it a good, hard shake. Strain into a Collins glass filled with ice. Garnish with fresh grated nutmeg on top.
