Add vodka, pomegranate juice, lime juice, and simple syrup to a cocktail shaker filled with ice.
Shake vigorously for 15-20 seconds until well chilled.
Strain into a Collins glass filled with fresh ice.
Top with a splash of club soda and stir gently with a bar spoon.
Garnish with a lime wheel and a few pomegranate seeds.
Notes
Store-bought pomegranate juice works well, but fresh-squeezed juice adds extra brightness.Make simple syrup by mixing equal parts sugar and hot water until dissolved. Store in the fridge for up to 2 weeks.For a mocktail version, replace vodka with additional pomegranate juice and club soda.The drink can be made in large batches for parties - multiply ingredients by guest count and mix just before serving.
