Heat a large pan to medium heat and add the ancho peppers. Dry toast them for 1-2 minutes per side, or until they puff slightly and become fragrant. Set into a bowl and cover with very hot water. Steep for 20 minutes, or until softened. Drain and add the softened peppers to a food processor.
In the same pan, add the pumpkin seeds. Heat at medium-low, stirring constantly, until the pumpkin seeds have all popped and toasted.
Add the sesame seeds and toast for 1 minute to brown.
Transfer to the food processor. Reserve some for garnish, if desired.
To same pan, heat 1 tablespoon lard (or vegetable oil) to medium heat and add the onion. Cook the onion until softened and lightly browned, 9-10 minutes.
Add the garlic and cook for 1 minute, until fragrant.
Transfer the onion and garlic to a food processor.
Add the spices, tortilla, and tomatoes to the food processor, then process to form a thick paste. You may need to scrape down the sides and process several times.
Heat the remaining 2 tablespoons lard (or vegetable oil) in the same pan to medium heat and add the paste. Heat through and cook for 5 minutes. The mole sauce should darken a bit.
Stir in 2 cup chicken stock and simmer at medium-low heat for 30 minutes, stirring occasionally, to let the flavors develop. Reprocess and strain if desired for a smoother mole sauce.
Taste and adjust for salt and sugar. |
