Distribution
Pekasam fish fermentation technique is widely distributed in Malay Archipelago; more precisely in Sumatra, Malay Peninsula, and Borneo.
Pekasam or Bekasam is widely distributed in Indonesia, especially in Gayo highlands in Aceh,[4]
Riau,[5] South Sumatra,[6] Kapuas Hulu in West Kalimantan,[7] Banjarmasin in South Kalimantan, and Cirebon in West Java.[8]
In Malaysia, the production of pekasam is concentrated at the northern end of the Malaysian peninsula in states such as Perlis, Kedah, Perak, and the Bornean state of Sarawak.[9]
In Malaysia, pekasam is the only fermented fish product that uses freshwater fish as the raw material, while in Indonesia, pekasam can be made of both freshwater fish or seafood.
Thin beef strips is also used to make pekasam instead of fish in Malaysia. Chicken, mutton and squid eggs are also available as pekasam. Unlike fish pekasam, these variants are frozen after preparation and can last up to six months.
As a preservation method
In Indonesia, pekasam as fish preservation method is quite widely distributed, especially in Sumatra, Kalimantan (Indonesian Borneo), and some parts of Java. The process of making fish pekasam or pickled fish takes more than a month. Initially, the fish meat used for the fish stock was preserved in the terracotta jar, mixed with salt, sugar and rice. The type of fish used in Cirebon pekasam is sailfish. In Cirebon, West Java, Pekasam or Bekasem is a special food prepared and consumed for Mawlid.[8]
