Golden Coffee Fizz

We've covered a few different fizzes (which emerge in the 1870s), but this one is the golden type (c. 1882), which means that there's no egg white in it, just egg yolk! We'll get into this more, but the "coffee" part comes from the Coffee Cocktail, a drink from our period of interest that contains no coffee but does contain brandy and port. Cacao and vanilla accent this drink perfectly.
