Add the honey, ginger, and water to a small saucepan and bring to a boil over medium heat. Lower heat to medium low and simmer for 3-5 minutes. Let cool to room temperature and strain before using.
To make the margarita:
Rim a glass by dipping it into honey ginger syrup and then into salt. Add crushed ice to the glass.
In a shaker add the tequila, lime juice, orange liqueur, and 1 ounce of the honey ginger syrup. Shake until well mixed. Pour into the rimmed glass with ice. Garnish with a lime wedge and serve.
