In a highball glass, combine Pimm’s No. 1, lemon juice, simple syrup, cranberry juice, ginger ale and ginger liqueur. Fill with ice and garnish with cranberries, lemon slices and rosemary sprigs.
Notes
Ginger beer can be substituted for the ginger ale.
You can make this into a large batch cocktail. Just add the ginger ale or ginger beer right before serving.
