Combine everything in a mixing bowl and let it rest in the fridge for 4 hours or overnight to develop its flavor.
Put the mixture into the hog casing using a sausage stuffer and divide according to desired length.
Generously prick the longganisa to release some trapped air. This will help to avoid bursting while cooking.
Refrigerate for another 3 days before cooking.
To cook, place the longganisa de recado in a pan and add 1/4 cup water. Let it simmer until the fat oozed out of the longganisa.
Let the longganisa de recado cooked in its own fat until golden brown.
