Ingredient notes & substitutions
Soda water - any sparkling water will do
Ginger shot/juice - make it yourself or get it from the store. Try to find a version with a high ginger content (they usually contain other ingredients as well, like apple juice).
Lemon needs to be fresh - bottled juice won't do
Fresh ginger is just for decorative purposes
Tips & tricks
If you don't have a cocktail shaker make the drink straight in a glass (or a pitcher if making multiple). Use chilled ingredients or add an ice cube to cool.
Rub the rim with the fresh ginger for extra spice
If your drink comes out too spicy from the ginger or too acidic from the lemon,just add a bit more soda water. This can happen as all ginger juices are made differently, and some lemons are more or less sour than others.
