Johnnie Walker Black Ruby makes the perfect base for this Christmas toast. Mix it with fresh lemon juice for brightness, a touch of raspberry syrup for that sweet, berry like note, and just a hint of simple syrup to tie it all together. The true magic, though, comes when you whisk in a tablespoon of lemon curd and add fresh raspberries for a burst of tartness. A silky layer of egg white then gives the drink its signature velvety texture.
