Wash the goat's tripe, lungs, small intestines and kidneys thoroughly and set aside the intestines.
In a medium size pot put the tripe, lungs, kidneys, whole garlic and crushed ginger with enough water just to cover the meat.
Boil for at least 15 minutes then drain. Let is cool and set aside.
In another pot, put the small intestines and fill with water just enough to cover the intestines.
Boil for at least 15 minutes then drain the intestines and set aside to cool. Save the green liquid from the boiled intestines which you will use later as papait.
Slice all the goat innards into tidbits. In a small pan saute garlic until fragrant then follow the onions and ginger and saute until the onions are soft.
Add the goat innards and saute for about 9 minutes or until the innards starts to produce oil.
Pour some fish sauce or patis and stir for 4 minutes then pour water just enough to cover the innards. Simmer for at least 1 hour or less or until the meat is tender. Add water if the liquid is evaporating too much.
Last but not the least add the siling haba, sinigang mix and the papait (the green enzyme).
Add the sinigang mix and the papait a little at a time until the desired bitterness and sourness is achieved.
Simmer for another 4 to 5 minutes and season with salt, pepper and granulated seasoning. Serve hot with steamed rice.
