Wash the pork thoroughly and put it in a big pot, fill it with 2 quarts water, bring to a boil in a high heat.
Skim the scum (dirty froth) that might float on top just before it boils, watch it because if you miss that moment, it’ll disintegrate and it will end up floating in your soup like “cobwebs”… not good.
After skimming the scum off add in the gabis (taro roots), tomatoes and onion and half the amount of green chili that you’re using.
Season with patis (fish sauce).
Bring to a boil again then lower heat to “gentle boil” or simmer.
If you have a pressure cooker, use it to shorten cooking time.
When meat is a little tender, add one large packet of sinigang mix, then boil some more until the meat is fork-tender.
Add the okra and the rest of the green chili peppers.
Cook for five minutes, then add in the kangkong leaves, and the last packet of sinigang mix, don’t add it all at once, have a taste again, add a little or the whole pack depending on how tart you want it.
Bring to boil and cook for another five minutes more or depending on how you want your veggies, al dente or mushy.
Taste it, adjust seasoning if necessary.
Serve hot with steamed rice and unbuckle your belts.
