Step 1

Trim off any large pieces of fat from the pork. Season all over with the salt and pepper, then place in a 4 1/2-quart or larger slow cooker. Pour in the pickling liquid and maple syrup. Cover and cook on the LOW setting until the pork is tender, 8 to 10 hours.

Step 2

Transfer the pork to a clean cutting board and shred with 2 forks or your fingers. Serve the pork on warm 6-inch corn tortillas with more pickled jalapeños, diced white onion, and chopped fresh cilantro.
