Method

How to make Penicillin

Follow the 6 reviewed catalog steps in order.

  1. 01

    Chill an old-fashioned glass and cut two or three thin coin-sized slices of fresh ginger.

  2. 02

    Place the ginger in a shaker and muddle firmly enough to release juice without grinding it into fibers.

  3. 03

    Add the blended Scotch, fresh lemon juice, and honey syrup, reserving the single malt for the float.

  4. 04

    Fill with ice and shake hard for 10–12 seconds until the drink is thoroughly chilled.

  5. 05

    Fine-strain over fresh ice in the chilled glass, then slowly float the single malt across the surface using the back of a spoon.

  6. 06

    Garnish with candied ginger slices and serve without stirring the aromatic float into the drink.

Why does this Penicillin list two Scotches?

Blended Scotch and single malt Scotch have separate measures and roles in this build. The single malt is the float; lemon, honey syrup and fresh ginger are also required. It is a cocktail name, not a medicinal claim.
