Instructions

  1. Step 1: In a small bowl, combine 1/2 cup white vinegar, 1/2 cup water, 1 tablespoon sugar, and 1 teaspoon salt. Add 1 medium thinly sliced red onion and soak for at least 30 minutes to quick-pickle.
  2. Step 2: Set Instant Pot to sauté mode and add the 3 pounds beef chuck roast pieces, browning them for about 3 minutes per side. Remove beef and set aside.

  4. Step 4: Return beef to the pot, coating with the sauce. Seal the lid and cook on high pressure for 60 minutes. Let natural release for 15 minutes, then quick release remaining pressure.
  5. Step 5: Remove beef and shred with two forks. Return shredded beef to the sauce and stir to combine.
  6. Step 6: Warm 12 small corn tortillas on a dry skillet over medium heat, about 30 seconds per side.
