Add the apple cider, calvados, Demerara Sugar Syrup, lemon juice, cinnamon and bitters to a tea pot and stir thoroughly. Pour into tea cups on saucers and garnish with rock candy stirrers.
Combine the sugar and 1 cup water in a small saucepan and bring to a boil. Cook, stirring, until the sugar dissolves. Remove from the heat and let cool completely. Keep covered in the refrigerator up to 1 month.
Optional: Soak a small box of golden raisins in calvados for 24 hours prior to use. Then, use the calvados to make the cocktail and serve the raisins on the side as a snack with the cocktail.
