What is bilimbi? Called kamias in the Philippines, averrhoa bilimbi is a tropical tree cultivated widely in Southeast Asia. The sour fruit can be eaten raw or used in cooking.
Why salmon belly? There are countries where the fish belly is thrown away. In some of the cookbooks I own, part of the tips in cleaning, cutting and preparing slices of fish is cutting off the belly, especially the section that contains the most amount of fat.
In the Philippines, fish belly is a delicacy. It is rich and delicious in a way that no description can give justice to. It’s the same with fish head. You just have to try it with the open mind of the curious and adventurous to appreciate it.
So, how is cooking salmon belly sinigang different from cooking sinigang with pork or chicken? How is cooking sinigang with kamias different from cooking sinigang with tamarind extract?
When cooking sinigang with chicken or pork, the meat is added during the early stages of cooking because they need time to simmer to tenderness. Not so with seafood — especially smallish pieces — which takes a much shorter time to cook. So, the salmon belly is added towards the end.
When cooking sinigang with kamias, I add the kamias, I include the kamias during the sauteeing. It needs time to soften to coax out the tartness. If added during the last stage of cooking, it won’t add much flavor to the broth.
As with any sinigang variant, I add the vegetables in stages starting with what takes longest to cook. For the vegetable combo in this recipe, my preferred order is okra, eggplant, thick stalks of the kangkong and thin stalks of the kangkong at two to three-minute intervals.
The salmon belly and kangkong leaves go in last. By the time the kangkong leaves wilt, the salmon belly is fully done (without being overcooked) and the rest of the vegetables are cooked through.
