Region 1 or the Ilocos Region is made out of four regions and a city—Ilocos Norte, Ilocos Sur, La Union, Pangasinan, and Dagupan City. Majority of the population speaks Ilocano, the third largest spoken language in the Philippines, although a significant number also speak Pangasinense.
The region has a coast and sloping extents that are prone to typhoon in the wet months, however devastatingly hot during the dry season. This is the setting of Ilocano food. It's salty because of the closeness to the ocean. There is even a whole territory named after asin (salt) in Pangasinan. Fish is preserved by drying, and of course, reduced into a paste or sauce by fermentation.
