Notes
To top off this drink, you can choose between ginger ale, ginger beer or sparkling lemonade. Experiment with different options to find the one that fits your preference.
If you can't decide between lemonade and ginger ale for your recipe, use both! Many recipes use both to top this famous drink.
Serve with a straw as the many garnishes can make drinking from the glass a bit cumbersome.
