Prepare a small basin or a big mixing bowl. Add in together the ground pork, salt, soy sauce, Worcestershire sauce, minced garlic and black pepper.
Mix all the ingredients by hand until all the ingredients are well combined.
Then add the sugar and continue mixing until the meat meat mixture becomes sticky.
To stuff the hog casing with the meat mixture, you will need a sausage stuffer. But you can use a plastic funnel with a large hole about 3/4 inch size.
Soak the hog casing first in water specially if you bought the dried hog casing.
Then insert the hog casing in the funnel tip until all the casing is inserted. Just leave an allowance of 1 1/2 inch at the tip.
Fill the hog casing with the meat mixture and allow the air to escape at the tip then close it by tying it up.
Fill the casing until almost full then divide at 2 inches each by pinching and twisting
Then tie the segments with the cooking twine or cotton crochet yarn. Cure the longganisa by hanging under the sun for 4 hours. Or you can just hang it in a dry place for 4 hours. Then freeze it to store it for a long time.
To cook the longganisa, put some water in a frying pan and boil the longganisa until the liquid has evaporated and the fat renders.
Stir cook to avoid burning and to cook it evenly on all sides. Stir fry until the sugar caramelize and the longganisa turns brown.
Serve with dipping sauce like spiced vinegar and cooked rice or fried rice.
