Use a meat thermometer to ensure pork reaches at least 195°F internally for perfect shredding. Browning the pork adds depth and richness. Adjust jalapeño heat as desired. Natural pressure release is key for tender meat. Broiling the shredded pork is optional but recommended for crispiness. Save the cooking liquid for tacos or rice. Variations include adding chipotle peppers, swapping citrus juices, using fresh oregano, or substituting protein for vegetarian or chicken options. Leftovers store in the fridge up to 4 days or freeze up to 3 months.
