Honey, ginger and lemon with Scotch and a smoky Islay float

Blended Scotch shaken with lemon and honey-ginger syrup, served over a big cube and topped with a float of smoky Islay whisky. Sweet, spicy and tart up front, with peat smoke rising from the glass at every sip. A soothing modern sour for cold evenings.

History

Created by Australian bartender Sam Ross at Milk & Honey in New York in 2005, as a riff on the Gold Rush, a house drink of bourbon, lemon and honey. It spread from bar to bar by word of mouth and became one of the most widely made modern classics.

Bartender's notes

  • Quick honey-ginger syrup: warm equal parts honey and water with plenty of sliced fresh ginger, steep for 20 minutes, then strain and cool.
  • Don't stir after floating – the smoky aroma should reach the nose before the honey and lemon reach the tongue.
