Matcha Cocktail

First make the basil simple syrup: In a small saucepot, combine the water and sugar and bring to a boil.
Stir until the sugar dissolves and then remove from the heat.
Add the basil and let cool to room temperature.
Remove the basil and transfer the simple syrup to an airtight container.
Store in the fridge for up to 2 weeks.
In a cocktail shaker filled with ice, combine the gin, lemon juice, matcha powder, and 2 tablespoons of the basil simple syrup.
Shake vigorously for 1 minute, until well chilled.
Strain into a glass filled with ice and top with club soda.
Garnish with a cucumber ribbon and basil sprig and serve.
