Add ice to fill shaker halfway and shake for 10–15 seconds.
Strain into a rocks glass with fresh ice.
Top with sparkling water or tonic water.
Stir gently and garnish with cranberries, rosemary, and citrus.
Notes
Use unsweetened cranberry juice for tartness and balance. Tonic water adds flavor, while sparkling water keeps it lighter. Fresh rosemary is essential for the herbal note. For a mocktail, skip the gin and add more cranberry juice.
