By the way, as I searched for more info on how National Mole Day came to be, I realized it wasn�t �Mole� the sauce; it was actually �Mole� the scientific unit of measure. Now, why would scientists name a unit of molecular weight after this delicious Mexican sauce? Anyway, enjoy the video (you can see the written recipe here), and if you have any secret mole-making knowledge, feel free to pass it along. Enjoy!
