- 5 dried chiles, mild to moderate heat level, such as guajillo, ancho, pasilla, New Mexican and/or mulato
- 1 container (32 oz.) beef stock (4 cups)
- 2 tablespoons olive or vegetable oil
- 1 2 1/2-lb. beef chuck roast (about 1 1/2 inches thick)
- 1 large or 2 medium onions, chopped
- 6 cloves garlic, sliced or chopped
- 1 tablespoon (a scant palmful) ground coriander
- 1 tablespoon (a scant palmful) ground cumin
- 2 teaspoons instant espresso powder
- 1 teaspoon dried Mexican oregano
- 1/2 teaspoon ground allspice
- 1 bottle (12 oz.) light beer (I used Corona)
- 1 rounded tbsp. light or dark brown sugar
- 1 tablespoon cayenne red pepper sauce, preferably Franks RedHot
- 1 tablespoon Worcestershire sauce
- 1 can (15 to 15.5 oz.) kidney beans, rinsed
- 8 soft white sandwich or hamburger rolls, toasted
- Sliced bread-and-butter pickles and chopped raw white onion, for topping
Stem and seed the chiles; transfer to a large saucepan. Add the stock; bring to a low, rolling boil over medium. Cook until the chiles soften and the stock is infused, 30 to 45 minutes. Working in batches, puree chiles and stock in a food processor to make the chile sauce.
Position a rack in the center of the oven; preheat to 325 degrees .
In a large Dutch oven, heat the oil over medium-high. Season the beef with salt and pepper. When the oil smokes, add the beef and cook until well browned, about 4 minutes per side; transfer to a plate. Add the onion, garlic, coriander, cumin, espresso powder, oregano and allspice to the pot; season and stir until the onions soften, just a few minutes. Add the beer and cook, stirring occasionally, until the liquid is reduced by about one-third, 8 to 10 minutes. Add the chile sauce, brown sugar, red pepper sauce and Worcestershire. Add the beef to the pot; cover and transfer to the oven. Cook until the meat is very tender, about 2 1/2 hours.
Place the pot on the stovetop; transfer the beef to a plate. Skim the fat from the juices in the pot. Using two forks, shred the meat and return to the pot. Mix in the beans; season, and cook until heated through, a minute or two. Divide the beef mixture among the roll bottoms, then top with some pickles, chopped onion and the roll tops.
