As you can see, there are so many different ways to make a mole. My absolute favorites always feature chocolate or cocoa though! Give a recipe a try if you have some time, or invent your own version!
I've served my chicken mole in small white corn tortillas, as I cannot get enough of the flavor and texture they bring to my tacos.
