For one Lychee Lemon Cooler cocktail, you'll need:
- 2 oz vodka
- 1 oz lychee liqueur
- 1 oz fresh lemon juice
- 1 oz simple syrup
- 2-3 fresh or canned lychees
- Club soda
- Ice
- Lemon slice and lychee for garnish
You can adjust the sweetness by changing the amount of simple syrup. For a non-alcoholic version, skip the vodka and lychee liqueur and add more club soda.
