Master's Tips
Professional insights to elevate your craft
Frozen drinks dull the perception of sweetness and acidity, so this recipe increases the lemon juice and honey-ginger syrup to compensate.
Avoid over-blending, which can lead to a watery consistency. Blend only until the mixture is smooth.
Do not blend the Islay Scotch with the other ingredients. The float is a critical component of the drink's aromatic profile.
