Step 1

In a small pan, toast the cloves, allspice and peppercorns until fragrant, about 3 minutes, stirring often. Add the thyme and oregano, toss for about 10 to 15 seconds, then pour the contents of the pan into a spice grinder and grind fine. Set aside.

Step 2

Add the sesame seeds to the pan you toasted the spices in and toast them, stirring often, until they just begin to brown. You need to keep an eye on this because they can burn easily. Move them to a bowl.

Step 3

Add the pecans and peanuts to the pan and toast, again stirring often, until you see some browning on the pecans, about 3 minutes. Move them to the same bowl as the sesame seeds.

Step 4

Grind finely all the nuts in a food processor or spice grinder. Set aside.

Step 5

Heat a cast iron frying pan or comal or other heavy pan over high heat. You'll want your oven fan on here. Start by setting the onions and garlic on the hot pan to char. You want the cut sides of the onion to be good and blackened. When they are -- the garlic will be ready, too -- peel the garlic and roughly chop the onion and put it in a blender.

Step 6

Set the tomatoes and tomatillos, cut side down, on the hot pan. Let them sit there for a solid 3 to 5 minutes. Use a thin metal spatula to remove them to the blender, scraping up all the blackened bits and adding that to the blender, too.

Step 7

If you are using a frying pan and not a comal, add 2 tablespoons of lard or oil to it. If you are using a comal you need to switch to a pan that has sides. Add the plantain and raisins and fry until the plantains are well browned and the raisins plump. Turn off the heat and stir in the breadcrumbs. Scrape out the contents of the pan into the blender.

Step 8

Add enough broth to the blender to allow it to spin correctly, and puree the fruits and vegetables well.

Step 9

Remove the stems from all the chiles. Collect all the seeds from the chiles and set them in a bowl.

Step 10

Here's the gnarly step: Heat the comal or frying pan on high heat. Turn the oven fan on high. Open the windows. Maybe get a facemask. Incinerate all the chile seeds. You want them black, carbonized. If you can do this outside, all the better. Once this is done, move the blackened chile seeds into a bowl of cold water.

Step 11

Now pour the cup of lard or oil into a pan and heat it to about 350F. Break the dried chiles into large pieces and fry them in the oil until very dark and crispy, about 5 minutes. You will need to work in batches, and you might need more oil. Press the chiles into the oil as they fry, because they will want to float. Once dark and crisp, move to a colander to drain.

Step 12

Once all the chiles are ready, submerge them in hot water to soften about 30 minutes. While this is happening, change the water on the seeds. This is important -- if you don't change the water on the seeds your mole will be very bitter. Do this twice over 2 hours. You don't need to change the water on the chiles themselves.

Step 13

When the seeds and chiles are ready, puree them in the blender with a little of the chile soaking water (not the seed water) and some of the broth from the vegetable step. Set aside.

Step 14

Almost there! In a large pot with a lid, add any remaining chile frying oil. You need a total of between 3 and 6 tablespoons. Get this oil hot over medium-high heat.

Step 15

Add the chile puree first. It will sputter and pop. Stir well to incorporate the lard or oil. Turn the heat down to medium and add the herbs and spices, the ground nuts, and the vegetable and fruit puree. Stir very well. Chances are this will be brown, not black. That's OK.

Step 16

Now it's time to very slowly cook your mole. Add the remaining broth, the chocolate and salt to taste. Drop the heat to low and cook your mole very gently, stirring every so often to make sure nothing burns on the bottom of the pot, for at least 30 minutes, and really up to 4 hours. You want the end mole to be thicker than gravy; you thin it later as you need it.

Step 17

As for what you're eating with your mole negro, you generally simmer the turkey or chicken or pork in broth mixed with a ladle of the mole until it's tender. Then you will want to serve it with finished mole, thinned to the consistency of melted ice cream, topped with toasted sesame seeds.
