Preparation

Cook the brisket

• Put the brisket ingredients in a 6-quart Dutch oven and cover with 10 cups of water. Bring to a boil over high heat and then reduce the heat to maintain a simmer and partially cover. Simmer until the meat is falling-apart tender,about 4 hours. Add hot water as needed during cooking to keep the meat submerged.
• Transfer the brisket to a cutting board and let sit until cool enough to handle. Reserve the cooking liquid. Scrape away and discard any fat from the brisket. Using your fingers or two forks, tease the meat into shreds. Cut the shreds crosswise into 1-inch pieces. Transfer the meat to a medium mixing bowl and moisten with 1/2 cup of the reserved broth. Save the remaining broth for another use (such as theBeefy Chelada Cocktail.)

Make the dressing

• In a blender, pulse the olive oil, lime juice, vinegar, garlic, 2 tsp. salt, and 1/2 tsp. pepper until mixed. Drain the canned chipotles, pouring all of the adobo sauce into the blender. Add chipotles to taste and purée the dressing. (One chipotle will give the dressing a little heat, two or three will produce a medium-hot dressing, four or more will make a fiery dressing.) Chop any remaining chipotles and serve them on the side, if you like.
• Add just enough of the dressing to the shredded beef to moisten it. Cover the bowl and chill it in the refrigerator for an hour or so.

To serve

• 冷却后,穿着会便便led in the bottom of the bowl; toss to redistribute. Transfer the meat to a serving bowl or platter and drizzle with a little more dressing. Serve cold, as is customary, at room temperature, or warm with the fresh tortillas, letting guests assemble their own tacos with the toppings of their choice. (You won’t need all of the dressing—serve the remainder on the side.)

Make Ahead Tips

You can make the beef brisket filling and the sauce up to five days ahead and refrigerate in airtight containers.
