How to Make It
In a spice grinder, combine the allspice, peppercorns and coriander and grind to a powder; stir in the cinnamon and 1/4 cup of salt. In a large bowl, toss the pork with the spice blend until well coated. Add the thyme and garlic and knead the garlic into the meat. Cover and refrigerate overnight.
Bring the pork to room temperature. Add the melted pork fat to a slow cooker with the pork and seasonings. Cover partially and cook over low heat until the meat is very tender, 4 hours, or up to 6 hours. Let cool slightly, then, using a slotted spoon, transfer the pork and garlic to a large bowl; discard the thyme. Mash the garlic and shred the pork, discarding any gristle. Stir in 1 cup of the fat and season with salt. Pack the meat into a ceramic bowl or individual crocks.
Reheat the fat and ladle a 1/2-inch-thick layer on top of the pork. Cover and refrigerate overnight. Discard the remaining fat or save it for another use. Serve the rillettes with toasts and the Pickled Apricots.
Rendered pork fat is available from farmers' markets or from prairiepridefarmminnesota.foodoro.com.
