Salt or sugar rim, if desired (I like to add lime zest to it)
Instructions
Combine a little lime zest with salt or sugar (your preference) for a rimmer. Wet the glass rim and dip in salt or sugar and set aside while making the cocktail.
Combine all ingredients except Fever Tree or club soda in cocktail shaker filled with ice. Shake well. Strain into a glass filled with some ice. Top with club soda.
