Muddle fresh ginger in a shaker and add the remaining ingredients, except for the Islay single malt whisky. Fill the shaker with ice and shake. Double-strain into a chilled old fashioned glass with ice. Float the single malt whisky on top.
The drink was created in 2005 by Australian bartender Sam Ross living in New York at the time. Its name derives from the drug penicillin, discovered by Scottish scientist Alexander Fleming, hinting to the medicinal properties of some of its ingredients, with suggested effects similar to that of a hot toddy which is said to relieve the symptoms of cold and flu.[2][3]
