Cocktail of the week: Prawn on the Lawn’s matcha whisky sour – recipe | The good mixer

A whisky sour with an earthy, verdant slant

This gloriously green drink matches the bright mood of early summer, when the countryside is bursting with verdant life. If you like, halve the amount of whisky and replace it with 25ml amaretto, for a sweet, nutty twist.
