How do you control sweetness?
Amaretto brings a pronounced almond character and sugar. Keep whisky dominant for a drier drink, or raise the liqueur carefully for a softer serve. Free-pouring can quickly upset a two-ingredient recipe.
Ice and stirring
Stir over ice until cold and strain into a rocks glass over one large cube. Small, wet ice dilutes the drink quickly; a large cube makes the serve more controlled.
Choose whisky for the serve
A light blend lets amaretto lead. A smoky whisky creates a drier, more assertive result. For a clear comparison, keep the measures fixed and change only the base spirit.
