Penicillin Cocktail Origins
This cocktail was created by Sam Ross at the famed New York bar Milk & Honey in the early 2000s. Ross set out to craft something comforting and layered, drawing on the similarities between the classic whisky sour and medicinal home remedies like hot toddies. The name is a playful nod to the ingredients’ reputation for soothing colds, though the drink is designed for pleasure rather than cure.
Ingredients and Substitutions
- Blended Scotch Whisky: Forms the base of the cocktail. Chivas Regal, Monkey Shoulder, or Famous Grouse work well. Avoid overly peaty options for the base.
- Islay Single Malt Scotch: Reserved as a float for the signature smoky aroma; Laphroaig is the classic choice but Ardbeg or Lagavulin are suitable substitutes.
- Honey-Ginger Syrup: The heart of the drink, blending soothing honey with fiery ginger.
- Lemon Juice: Freshly squeezed is essential for brightness and balance.
Substitution tips:
- Other whiskies: You can experiment with rye or bourbon, but you’ll lose the Scotch’s distinctive character.
- Alternative sweeteners: Maple syrup or agave can replace honey in a pinch, altering the flavor profile slightly.
- Preserved ginger: If fresh ginger isn’t available, ginger syrup or candied ginger can stand in, but the intensity will vary.
