2. Heat up a wok on medium fire. Put the pork fat in the wok and let it sizzle. After about 3 minutes, you will start to see the oil oozing out from the pork fat and let it render the fat. Turn the heat to low and continue to fry the pork fat until the pork fat pieces turned crispy, crunchy and golden. Drain and separate the lard from the fried pork fat. Set aside.
