3/4 oz Raspberry Syrup (*)
1/2 oz Lime Juice
Build in a Highball glass filled with ice. Stir to mix and top with ginger ale. Garnish with a lime wedge and add a straw.
(*) Green Street's raspberry syrup is only lightly sweetened and less sugary than a 1:1 simple syrup. Perhaps with a sweeter raspberry syrup, a 1/2 oz would be better here.
