Trachang Shrimp Paste or shrimp sauce is made from fermented ground shrimp mixed with salt. Some versions are in its wet form such as those in Vietnam and other versions are sun dried and either cut into fist-sized rectangular blocks or sold in bulk. It is an essential ingredient in many curries and sauces. Shrimp paste can be found in most meals in Myanmar, Laos, Thailand, Malaysia, Singapore, Indonesia, Vietnam and the Philippines. It is often an ingredient in dip for fish or vegetables. In Thailand shrimp paste or shrimp sauce (kapi) is an essential ingredient in many types of nam phrik, spicy dips or sauces, and in all Thai curry pastes, such as the paste used in kaeng som. Very popular in Thailand is nam phrik kapi, a spicy condiment made with fresh shrimp paste and most often eaten together with fried pla thu (short mackerel) and fried, steamed or raw vegetables. In southern Thailand there are three types of shrimp paste: one made only from shrimp, one containing a mixture of shrimp and fish ingredients, and another paste that is sweet.
