The story
Created by Sam Ross in 2005 while at Milk & Honey in New York City. The name refers to the drink's honey-ginger combination, which is reminiscent of folk remedies, while the smoky Islay Scotch float serves as the 'medicine.'
Variations
Some versions use ginger syrup instead of fresh muddled ginger. A garnish of candied ginger or a lemon peel can be added. The ratio of blended to Islay Scotch can be adjusted for more or less smokiness.
Host tips
The quality of the Islay Scotch makes a significant difference. Properly floating the Islay Scotch creates layers of flavor as you drink. Fresh ginger is essential for the proper spicy kick.
