Although tamarind is the most popular, and common, ingredient for flavoringsinigang, other fruits likekamiasmay be used. When cookingsinigangwith seafood instead of meat,bayabas(guava) is the souring agent of choice.

When cooking sinigang with pork (or beef), choose a cut with bones because it is the bones that make the broth rich and full-bodied. Pork tail is traditional but we prefer ribs or bone-in belly because they are meatier.

And because we don’t like scum to boil into the broth, we parboil the pork. The pork ribs are left to boil for about ten minutes to allow the scum to float on the surface of the water.

Rinsing parboiled pork ribs under the tap before simmering

Instead of skimming off scum which can be a tedious process, the parboiled pork is drained and rinsed under the tap. Goodbye, scum. The rinsed pork goes into a clean pot, covered with water and simmered with fish sauce.

The vegetables are cooked in a separate pan when the pork is more than halfway done. The spice base consists of shallots, tomatoes, garlic and finger chilies.

As for the vegetables, there are many vegetables that can go into a pot of pork sinigang. Kangkong (water/swamp spinach), sitaw (yard-long beans), talong (eggplants), labanos (radish) okra and gabi (taro) are traditional — add all of them or only some of them, it’s really your choice. For this recipe, we used kangkong, talong and labanos.

Make sure to rinse the kangkong well (it grows in swamps after all) before cutting. When you cut the vegetable, separate the stalks and leaves because they will not go into the pot at the same time.

Sauteeing shallots, garlic, tomatoes and finger chilies

With the pork simmering in one pot, saute the shallots, garlic, tomatoes and chilies in another. Once they soften, take as much broth from the pot with the pork as you can leaving just enough for the pork to continue simmering in. Add the broth to the pot with the sauteed vegetables. When the broth comes to a boil, start adding the vegetables.

Adding kangkong stlaks, eggplants and radish to sinigang

Because a variety of vegetables are used to make sinigang, it is important to drop them one by one into the pot. Normally, I add the kangkong stalks and radish first. But with mature kangkong such as the kind used here, the stalks take longer to cook than usual so they were added first.

Meanwhile the radish was quite young which translates to a shorter cooking time. So, they went into the pot at the same time as the eggplants.

Adding kangkong leaves to pork ribs sinigang

Last to go into the pot are the kangkong leaves which require only a few minutes to wilt and get cooked through. The cooked pork is added at the same time as the kangkong leaves.

The tamarind extract goes into the pot at this point too. After five minutes of simmering, the meat and vegetables have had sufficient time to soak up some of the tartness of the tamarind extract.
