Zalatina is best made a day ahead — overnight chilling gives the aspic time to set beautifully and allows the flavors to deepen. Serve sliced directly from the container with crusty bread, olives, and a squeeze of fresh lemon. A small glass of ouzo or tsipouro alongside is traditional and highly recommended. For storage, keep covered in the refrigerator for up to 5 days. The dish can also be frozen for up to 2 months — thaw overnight in the refrigerator before serving. If you cannot find pigs ears, simply omit them and increase the pork shoulder slightly. The collagen in the pigs feet is essential for setting the aspic, so do not substitute these.
