Cocktail of the week: Black Lacquer’s like a stone – recipe | The good mixer

A distinctly Japanese plum gin and tonic with a whiff of the sea

This Japanese plum liqueur cocktail with a seaweed-infused syrup is just the thing to take the edge off a long winter’s day. For a booze-free alternative, simply dilute some syrup with tonic to taste.
