Tips
Let the pressure release naturally for maximum tenderness - rushing this step can result in tougher meat.
Save the cooking liquid to add back if the shredded beef seems dry, or use it as a flavorful base for soup.
For extra heat, add a diced jalapeño or chipotle pepper to the spice mixture before cooking.
