Shrimp pastes may vary in appearance from pale liquid sauces to solid chocolate-colored blocks. Shrimp paste produced in Hong Kong and Vietnam is typically a light pinkish gray while the type used for Burmese, Lao, Cambodian, Thai and Indonesian cooking is darker brown. While all shrimp paste has a pungent aroma, that of higher grades is generally milder. Markets near villages producing shrimp paste are the best places to obtain the highest quality product. Shrimp paste varies between different Asian cultures and can vary in smell, texture and saltiness.
Terasi, an Indonesian variant of dried shrimp paste, is usually purchased in dark blocks, but is also sometimes sold ground. The color and aroma of terasi varies depending on which village produced it. The color ranges from a soft purple-reddish hue to darkish brown. In Cirebon, a coastal city in West Java, terasi is made from tiny shrimp (Acetes) called rebon, the origin of the city's name. In Sidoarjo, East Java, terasi is made from the mixture of ingredients such as fish, small shrimp (udang), and vegetables. Terasi is an important ingredient in Sambal Terasi, also many other Indonesian cuisine, such as sayur asam (fresh sour vegetable soup), lotek (also called gado-gado, Indonesian style salad in peanut sauce), karedok (similar to lotek, but the vegetables are served raw), and rujak (Indonesian style hot and spicy fruit salad).
On the island of Lombok, Indonesia, a more savory and sweet shrimp paste called lengkare is made.
