sinigang

Sinigang is Tagalog, related to the root sigang (to stew). The soup is defined by its sourness — the souring agent is typically tamarind (sampalok), though calamansi, green mango, guava, or kamias (bilimbi) can be used. The protein is usually pork ribs, shrimp, or fish. Vegetables — kangkong (water spinach), radish, eggplant, string beans, tomatoes — are added near the end. The broth should be clear, thin, and aggressively sour.

Sinigang is pre-colonial Filipino. The technique of souring a broth with native fruits predates the Spanish colonization of the Philippines (1565-1898). The sour flavor profile is distinctly Southeast Asian — found also in Vietnamese canh chua and Thai tom yum. But sinigang's sourness is less sweet than Thai and less herbal than Vietnamese. It is direct. The tamarind hits and does not apologize.

A 2021 international taste-mapping study by TasteAtlas ranked sinigang as the best soup in the world, ahead of Vietnamese pho and Thai tom yum. This result, while methodologically questionable, was a source of intense national pride in the Philippines. Filipinos shared the result millions of times. Sinigang had been validated by an international audience, which mattered more than it should have.

In Filipino households worldwide, sinigang is the soup of homecoming. It is what Filipino mothers cook when their children visit. It is what overseas Filipino workers crave. The sourness is specific — not citrusy, not vinegary, but tamarind-sour, a particular acidity that comes from a particular fruit in a particular broth. The craving is for that particular acidity. Nothing else satisfies it.
