Notes
The drink can be made non-alcoholic by skipping the vodka and adding more ginger beer.Store leftover lychee syrup in an airtight container in the fridge for up to 2 weeks.Fresh lychees can replace canned ones when in season. Peel and pit them before use.For extra ginger flavor, muddle a small piece of fresh ginger in the shaker before adding other ingredients.
