Chill Your Glass: Begin by cooling your glass with ice to ensure your cocktail stays refreshingly cold.
Combine Ingredients: In a shaker, combine all the ingredients except the elderflower tonic and garnishes.
Add the Gin: Pour in the Roku Gin.
Shake Vigorously: Fill the shaker with ice and shake well for about 10 seconds until the shaker is cold to the touch.
Strain and Serve: Fine strain the mixture into your chilled glass filled with fresh ice.
Top and Garnish: Gently splash the elderflower tonic over the top. Garnish with an apple blossom flower, elderflower, and a shiso leaf.
