Fairytale of New York

For Winter Warmth Syrup: Combine water, sugar, apple, pear, cinnamon sticks, cloves, and nutmeg in a saucepan over medium heat. Bring to a simmer, stirring until sugar dissolves, and simmer for 15 to 20 minutes. Cool and strain.

For one drink: Place orange peel, syrup and bitters in a low glass and muddle. Pour in whiskey and add a large ice cube.

For a carafe: The source describes using all the syrup and about 5½ cups bourbon for two 4-cup carafes.
