Place the rubbed pork into the cooker.
Place the rest of the ingredients (orange juice, lime, garlic, onion & jalapeño) on top of the pork.
Lift one side of the pork up (use a tong or wooden spoon); this will allow the juice to go underneath the meat.
Place the lid on. Pressure cook on high for 80 minutes and a natural release (approx. 30 minutes). Remove the lid.
Remove the pork an place on a bowl/plate. Use tongs or 2 forks to shred the meat. Set aside.
Strain liquid from cooker using a fine wire mesh. Save the liquid for frying.
