Mole Negro Oaxaqueno: Oaxacan Black Mole Recipe

– adapted from My Search for the Seventh Mole by Susana Trilling

Oaxacan Black Mole from Susana Trilling is a well known and beloved recipe, popularized by Chicago’s Rick Bayless and featured in several cooking shows. It was the ideal starting point for a lesson in learning how to make this culinarily important sauce. The recipe in the book is made with chicken but Susana describes how this sauce is traditionally served with turkey instead of chicken, and beef or pork is sometimes added to enhance the flavour. For this blog, we will use pork of course!

The recipe is recommended with chicken, but we were curious to see how it the mole recipe would work with pork. It turns out that the recipe makes a very large quantity of mole so there was enough to fork off a variation using pork shoulder, but we had to start the pork cooking on its own ahead of time so that it could be served when the mole was ready. The mole itself takes several hours to prepare so we used the sous vide technique to start the pork cooking the night before.

Susana recommends that mole is served with a large stack of fresh corn tortillas. These can be purchased from a specialty store but they’re also easy to make at home if you have a tortilla press and masa harina flour. Rick Bayless has a good recipe and instructions for them on his website.

Makes 12-16 generous servings of mole. Leftovers go very well with steamed rice and a fried egg.

Notes for success

  • The mole recipe makes a great deal of sauce (about twice as much as needed for the specified quantity of meat) but it keeps well and the flavours get better after a day or so. Leftover sauce can also be frozen.
  • The mole recipe makes enough for the amount of chicken, pork and cheese specified in this post.
  • The meat and the sauce can be made up to several days and reheated before serving.
  • When handling spicy chiles and their seeds, be careful not to rub your eyes at the same time.
  • Remove the seeds from the dried chiles, set the seeds aside, and soak the dried chile bodies in cold water several hours ahead or the night before making the mole sauce.
  • Toast the chile seeds in a well vented location (i.e. turn on the stove exhaust and open the windows). The seeds will smoke; take care not to breathe in the spicy oils.
  • Have the remainder of the Mole ingredients ready before making the sauce. Grouping the sauce ingredients together in the order that they’re cooked will simplify and speed things up.
  • A powerful blender such as a Vitamix makes this recipe much easier to put together.
  • Pork shoulder is a very flavourful meat to have with mole sauce but it requires a longer cooking time in order to to become tender.
  • This post includes instructions for cooking pork shoulder sous vide ahead of time. It can be started the night before or very early morning on the day of serving.



  1. Cut the pork shoulder into 1” cubes and place into a large mixing bowl. Add the salt and pepper and mix well.

  1. Break open each of the dried chiles with your hands and empty the seeds into a separate bowl. Reserve the chile seeds and set aside.
  2. Place all of the dried chile bodies into a bowl and cover with cold water. Allow the chile bodies to soak for several hours or overnight.

Oaxaca Black Mole Negro Recipe Dinner Party 09Chile seeds, before toasting

  1. Place chile seeds on a heavy bottomed pan, preferably cast iron. Heat the pan over medium high heat until the seeds are blackened, stirring occasionally, about 20 minutes. Some seeds may jump out of the pan; cover the pan with a splatter screen if one is available.
    Note: Try to do this in a well-ventilated place because the seeds will give off very strong fumes.

  1. Remove the blackened seeds from the heat and place them in a bowl. Soak the blackened seeds in 1 cup of cold water for 10 minutes. Drain the seeds and cover them with more water. Let them soak for another 15 minutes more, then strain them.
  2. Add the seeds to the blender with the chiles and blend for about 2 minutes. The chile paste should be silky smooth, with no noticeable pieces of chile skin.

  2. Blend well for several minutes, until the mixture is very smooth.

Mole: Sauce

Oaxaca Black Mole Negro Recipe Dinner Party 12Chocolate pieces, Ground Ingredients, Chile Paste, Tomato Puree

  1. Have the chile paste, ground ingredients, tomato puree and chocolate pieces ready.
  2. In a heavy 6-quart stockpot, heat 2 Tbsp of lard or oil until smoking and fry the chile paste over medium to low heat, stirring constantly so it will not burn, for approximately 20 minutes.
  3. When it is “bubbling furiously”, add the tomato puree and fry until the liquid has evaporated, about 20 minutes.
  4. Add the ground ingredients to the pot. Stir constantly until everything is well-incorporated, about 20 minutes.
  5. Add 1 cup stock to the mole, stir well, and allow to cook 30 minutes, stirring occasionally. Add the salt.
  6. Break up the chocolate and add to the pot, stirring until it is melted and incorporated into the mixture. Taste the mole and add additional salt to taste.
  7. Toast the avocado leaf briefly over the flame if you have a gas range or in a dry frying pan and then add it to the pot – or – If avocado leaf is unavailable, add the piece of star anise.
  8. Slowly add more stock to the mole, as it will keep thickening as it cooks. Continue to cook for 30 minutes, stirring occasionally so it does not stick, and adding stock as needed. The more time it has to cook, the better. There should be no gritty texture (from the seeds), which will cook out over time. The mole should not be too thick; just thick enough to coat the back of a spoon.
  9. If making a vegetarian cheese option, remove 1 cup of the mole and place into a separate saucepan.
  10. Heat the corn tortillas in a microwave and keep them covered so that they do not dry out.

To Finish: Pork

  1. The pork should be cooked tender firm from the sous vide bath.
  2. Open the sous vide bag and drain the pork juices into a separate bowl. If the pork is cooked far enough in advance, the pork juices can be used instead of chicken stock for the mole sauce.
  3. Add the pork to the mole sauce to heat through. The pork can also be left simmering in the mole for the last 30-60 minutes of the mole’s cooking time.
  4. Serve with hot corn tortillas.
