Fill a large pot with water, add a pinch of salt, and bring to medium-high heat. Add the pork fat and blanch for about 5 minutes. Remove and set aside.
Once slightly cooled and firm, dice the pork fat into pieces about 0.5 inches thick. Keep in mind they will shrink during frying, so don’t cut them too small.
Place the diced pork fat into a large non-stick skillet. Add enough water to almost cover the fat. Turn heat to medium and stir gently.
As the pork begins to turn lightly golden, add the optional ginger, garlic, and shallots. Reduce heat to medium-low and let it simmer. Stir occasionally to prevent sticking.
Remove the aromatics. When the pork pieces float and turn golden brown, immediately strain them out to avoid overcooking.
Let the crispy lard cool completely, then store in an airtight container.
The rendered lard oil can be stored separately and used for cooking, such as stir-frying or drizzling over dishes.
