For Basil-Spiced Simple Syrup, bring sugar, water, cinnamon sticks, cloves and basil to a gentle boil in a small saucepan over medium-high heat; reduce heat. Simmer, uncovered, for 8 to 10 minutes or until reduced to ½ cup. Strain through a fine-mesh strainer set over a bowl; discard spices and basil. Cool syrup. Store covered in refrigerator for up to 1 week.

For each drink, muddle gingerroot in a cocktail shaker. Add Triple Sec, lime juice, Basil-Spiced Simple Syrup, orange bitters and ice to the cocktail shaker. Cover and shake well until chilled.

Strain into 1 (10-oz.) ice-filled cocktail glass. Garnish with orange slice and basil, if desired.
