make the salad
In a medium saucepan, cover the pork with the water and Chicken Stock. Add the onion, carrot, celery, bay leaf, 1/2 teaspoon of salt and the peppercorns and bring to a simmer. Reduce the heat to low, cover and simmer, skimming occasionally, until the meat is very tender when pierced with a knife, about 2 1/4 hours. Transfer the meat to a plate and let cool completely, then coarsely shred with 2 forks. Strain the stock and refrigerate until chilled; discard the vegetables. Discard the fat from the stock and boil over high heat until reduced to 1 1/2 cups.
