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!
