Notes
The drink can be made sweeter by adding more lavender syrup.For a stronger lavender taste, muddle fresh lavender in the shaker before adding other ingredients.Store-bought lavender syrup works well, but homemade syrup offers better flavor control.Keep garnishes simple - too many additions can overwhelm the drink's delicate flavors.This recipe serves one person and takes about 5 minutes to prepare.
