This is good but not that authentic. You can use baking cocoa instead of Mexican chocolate which has a lot of sugar. This is probably one of the better recipes. You don't need a zillion ingredients to make mole. I make it all the time and my recipe is a secret and fairly easy. Authentic enchilada gravy and mole do not use tomatoes. Tomatoes are an addition for non-Mexican tastes. I am a huge fan of mole and when I go to Mexico I order Pollo en Mole for just about every meal!

This mole pairs well with any kind of cooked fish, tofu, vegetables or just beans and rice.
