Also Sinigang na baboy, Sinigang na hipon, Sinigang sa sampalok
A sour soup of pork, prawns or fish with vegetables, soured most often with tamarind.
What makes it sinigang
Sour first — sharp enough to make you wince a little.
A clear broth with meat or seafood.
Vegetables added in order: radish, long beans, aubergine, water spinach last.
Where it comes from
It's the soup many Filipinos call home. Its sourness is the point, and it comes from whatever is to hand: young tamarind most of all, but also green mango, guava, kamias, calamansi, or batwan in the Visayas.
It's eaten with rice, the broth spooned over, and often a little fish sauce with chilli on the side for dipping the meat.
How it varies
Sinigang na hipon
With prawns, cooked only briefly.
Sinigang sa bayabas
