As you can see, the Guadalajara Cocktail is actually a pretty simple one, just four ingredients. Of course there are more simple cocktails out there, but this one is pretty easy. As with so many relatively simple mixtures like this, it just goes to show that you don't need a lot of complexity or lots of ingredients to make a tasty drink. That being said, some of the ingredients in this cocktail recipe aren't the most common for household bars, especially the Fernet and the Mole Bitters. Unfortunately there's not really much to replace these ingredients with, but it is a good opportunity to expand your bar somewhat!
