Now...you may look at this and say..."Egg Drinks? WTF?" I did....lol. Apparently, there are quite a few classic drinks that actually call for an egg to be used. A well known example, of course is Egg Nog.
Personally....I don't care for Egg Nog. Never have, probably never will. It's a texture thing :) A list of other drink recipies that call for the ever humble egg can be found here.
