Build in glass over ice, stir, rest, sip.
Commercially available barley malt syrup is optimized for baking, not stirring, so to make it work in this drink I heat a bit of it in water on the stove until the color and flavor have mixed in. Malta sodas, such as Goya and India, have a similar flavor and can be substituted, but be careful as they are both very sweet and overwhelmingly flavorful. You want the barley to accent the whiskey, not engulf it.
