First, prepare the honey-ginger syrup. Here are some options:
Alternative #1: Combine 1 cup of honey with one 6-inch peeled and sliced piece of ginger root with 1 cup of water in a small pot and bring to a boil. Reduce the heat and simmer for 5 minutes. Refrigerate overnight, then strain, discarding the solids.
Alternative #2: Muddle 2-3 healthy quarter-size slices of fresh ginger in the bottom of your cocktail shaker before starting to make your cocktail.
Alternative #3: Use a ginger liqueur and add 3 bar spoons of a 3:1 mix of honey syrup.
Combine the blended Scotch with the honey-ginger syrup and lemon juice in a cocktail shaker three-quarters filled with ice. Shake until well chilled. Strain into a rocks glass with ice. Top with the Islay Scotch and garnish with fresh or candied ginger.
