Take a tangerine or orange slice and moisten the rim of a rocks glass, then coat the rim by dipping it into the cinnamon sugar mixture. Add ice to fill the glass.
Into a cocktail shaker, pour pomegranate juice, tangerine juice, tequila, orange liqueur, honey, vanilla extract, ground cinnamon, ground ginger, and a pinch of cayenne pepper.
Add ice to the shaker, put on the lid, and shake for 15 seconds until thoroughly chilled.
Pour the cocktail through a strainer into the prepared rocks glass over fresh ice.
For a bubbly, festive touch, add a splash of ginger beer. (optional)
Finish with a cinnamon stick as garnish.
