Sticks of belacan produced in Bangka Island, Indonesia
Belacan, a Malay variety of shrimp paste, is prepared from small shrimp from the Acetes species, known as geragau in Malaysia or rebon in Indonesia. In Malaysia, the krill are typically steamed first, then mashed into a paste, and kept in storage for several months. The fermented shrimp are then prepared, fried and hard-pressed into cakes. William Marsden, an English writer, included the word in his "A Dictionary of the Malayan Language" published in 1812.
