I can count on one hand the number of Scotch-based cocktails worth mixing. Scotch does not “play well with others,” which is okay by me.

Among those Scotch-based libations that are worthy, Penicillin is a refreshing drink that smoothes out the rough edges and wets one’s whistle quite admirably.

This version is a subtle variation. Usually made with honey-ginger syrup as the sweetener, I substituted Canton (Ginger Liqueur) instead. It achieved the same goal of providing a gingery sweetness against the lemon Juice, and brought a few percentage points of alcohol to the party.

I bring you Penicillin:

2oz. Blended Scotch (I used Chivas)

3/4oz. Lemon Juice

3/4oz. Honey-Ginger Syrup (I used Canton)

1/4oz. Islay Malt

Shake everything but the Islay with crushed ice. Strain into a cocktail glass or coupe and float the Islay on top of the cocktail. Garnish with dried ginger.
