Tiquirí

For vanilla cane syrup, simmer 2 cups cane sugar, 1 cup boiling water and 1 split vanilla bean for 15 minutes, then strain and cool. Shake all listed measured cocktail liquids with large ice cubes for at least 20 seconds and pour the entire contents, including ice and pulp, into a mule mug. Coat the lime wheel with cane sugar and use as garnish.
