Siomay or Somai (Chinese: 烧卖; Pe̍h-ōe-jī: sio-māi), is an Indonesian fish dumpling (wonton wrapper) steamed with vegetables, served with peanut sauce or sweet and sour sauce.
It is a variant of the Chinese Shumai (pork-based dumpling) and, just like bakso, lumpia, and pempek, it has been influenced by Chinese-Indonesian cuisine.
It is considered a light meal, similar to those served in Chinese dim sum.
It is traditionally made with pork, but is often substituted with tenggiri (Spanish mackerel) as many Indonesians observe halal dietary law.
Sometimes, other types of fish like tuna, mackerel, and shrimp may also be used to make siomay.
Traditional accompaniments include: steamed cabbage, potatoes, bitter melon, boiled egg, and tofu.
Siomay is often cut into pieces and served with peanut sauce or sweet soy sauce (kecap manis), or sweet-sour sauce with a squeeze of lime juice.
However, Indonesian siomay is rarely served with peanut sauce; instead, it is served with a sweet and spicy chili sambal sauce, or without sauce, resembling authentic Chinese shumai.
Having long been assimilated into Indonesian cuisine, the most famous version of the dish is the Bandung-style siomay (siomay Bandung).
My version is shrimp-based and served with sambal sauce.
