The original Blackberry Smash that I drank was described on the menu at the restaurant where I first sampled it as a "Bourbon based drink with lemon-verbena and blackberries". My Internet research showed that the base recipe for the drink is Bourbon, blackberries, mint and soda water. I tried making the drink with both lemon and lime, various sodas, flavored simple syrups, etc. I think that my recipe shows the Bourbon off to its best advantage because the ginger and spice bring out the smokiness of the alcohol. I would not suggest more than one and a half of these drinks...and the half is only on offer because it is too good a cocktail to only have just the one!'
