Just put about a teaspoon of instant coffee in my coke, expecting a quick-but-gross boost.
It is the single most delicious flavored soda I've ever had (although it is with difficulty that I restrain myself from using exclamation points at the end of each sentence).
Anyone else do anything like this? What do you put in your sodas to make them your own?
By the way--thanks to those who responded to my recipe translation question--in the process of locating epifin locally or by mail order.
