Penicillin

Floating the Islay Scotch will provide a strong, smoky nose to the cocktail. If you prefer, you could instead add it to the shaker in order to create a more homogenous cocktail. 

If you don’t feel like making ginger syrup for this, you can try using fresh ginger instead: Add 3 or 4 ginger slices into your shaker before any of the other ingredients and muddle it firmly. Continue making the cocktail as detailed above, and make sure you double-strain to prevent any ginger fibers from making it to your glass.

If you’re making lots of these, consider making a honey-ginger syrup and save yourself some time while pouring.

The Penicillin was created by Sam Ross in 2005 while working at Milk & Honey in New York, USA. Ross was initially making a riff on a Gold Rush using Islay scotch instead of bourbon, and eventually landed on one of his most celebrated cocktails.
