Sarawak belacan is a type of fermented shrimp paste from the Malaysian state of Sarawak on Borneo Island. It is made from small shrimp or krill that are salted, fermented, and then dried under the sun. Known for its intense umami flavor and pungent aroma, Sarawak belacan is a key ingredient in many traditional Malaysian dishes, adding depth and complexity to sauces, soups, and stir-fries.
