Sourness, according to Doreen Fernandez, “is a favored Philippine flavor.” Just how sour is sour? “Sour enough to savor, to make the lips pucker and the eyes squint slightly, and yet not too sour—just at the point of perfection.” In the spectrum of sensation, sourness can be both sharp and sudden, an acetic shudder down the spine. Asim, the Tagalogs call it. From the earliest written records about the Philippines, it is this taste that has come to define our cooking. “Spanish colonials from the 1500s through the 1800s described indio food as primarily salty and sour,” writes food historian Felice Prudente Sta. Maria. “Both tastes can induce sweat in hot climates and remind the body to keep hydrated and its electrolytes balanced.” Let us trace the pathways of this taste as it evolved in three key dishes: sinigang, kinilaw, and adobo.
