I read on another forum that sprite and a splash of coke created a substitute for ginger ale. Maybe the placebo effect with the ginger color, but whatever gets you through the night. Tried it with a shot of Woodford Reserve, seems to do the trick.
We used to do this at a bar/restaurant I worked at in college. It works 9.5/10 times. Especially when mixing it with something. Ginger ale doesn't have real ginger any more anyway it's all artificial. Most people would not like the real stuff any more.
