The blue moon cocktail - although not as popular as other whisky-based cocktails - is an elegant libation that combines smooth whisky with the delicate sweetness of sherry. Using minimal ingredients to create a simplistic yet smooth drink, experiment with bitters of choice for more variation.
Add all the ingredients to an ice-filled mixing glass.
Stir to mix, chill and dilute.
Strain over an ice ball in a rocks glass.
Garnish with an edible flower and serve.
