I found these recipes in the April 2008 issue of the magazine 'Australian Good Taste'. Apparently, this coffee-flavoured cocktail was first mixed at the Hotel Metropole in Brussels in 1949. Cola Black Russian and White Russian with Vodka and Cream are obviously direct descendants of Black Russian! How much cola you use in Cola Black Russian and how much cream you use in White Russian with Vodka and Cream will obviously depend both on the size of your glass and the portions that best suit your taste preferences! There is an inconsistency in the spelling of "'Kahlúa" in this recipe because Zaar would not accept this spelling in the list of ingredients. Intriguing! Not to worry: just relax and enjoy your choice of Black Russian, Cola Black Russian or White Russian With Vodka and Cream.
