Fill a shaker with ice and add vodka, blood orange juice, and lime juice.
Shake for 10–15 seconds until chilled.
Strain into the chilled mug filled with fresh ice.
Top with ginger beer and stir gently.
Garnish with a blood orange slice or lime wedge.
Notes
Use spicy ginger beer for a stronger contrast to the sweet citrus. Add more lime juice if using mild ginger beer. Blood orange adds stunning color and flavor depth.
