Technique Notes
Float the Islay on the back of a spoon and do not stir it in. The peat is meant to arrive through the nose on every sip, not to be part of the body.
Why the Penicillin Works
The Islay float is the trick — peat smoke enters through the nose on every sip while the blended Scotch carries the structure underneath. Ginger and honey are an old folk-medicine pairing that lemon ties together with acid, and the smoke transforms a sour into something that feels medicinal in the best sense.
