A bright, citrus-forward riff on the classic Hemingway special, with cherry depth and a clean white rum base.

Papa doble

Serves 1

50ml white rum – we use Havana Club 3 Años
35ml fresh grapefruit juice
20ml fresh lime juice
15ml cherry liqueur – we use Bellamie
1 cherry, or 1 twist grapefruit peel, to garnish

Measure all the liquids into a shaker filled with ice and shake hard until very well chilled. Double strain into a rocks glass filled with fresh ice, then garnish as you wish – a cherry or a twist of grapefruit peel both work well.
