Cook the roast

  5. Transfer the roast to a platter and tent loosely with foil.
  6. Rest for 10 minutes.
Make the gravy

  2. Whisk the cornstarch and cold water in a small bowl until smooth.

For the best texture, cook until the roast is fork-tender before shredding. Refrigerate leftovers in an airtight container for 3 to 4 days; freeze leftovers yes.
