Jamaicans celebrate a holiday at Christmas, the Jonkonnu, which the Irish naturalist Sir Hans Sloane described in the 1700s: People dressed in masks with ox horns and boar tusks marched from house to house celebrating, some suggest, the exploits of John Canoe, a local hero who fought against the colonizing forces. So enjoy, like a Jamaican in the middle of Jonkonnu, this warm and sweet gin, with its Jamaican pepper and its Santa Claus costume. Perfect Serve: 50 mL XMAS, 200 mL fever tree Indian tonic, twist of mandarin.
