Siomay is ubiquitous in Indonesian cities. It can be found in street-side food stalls, travelling carts, bicycle vendors, and restaurants. Just like bakso, lumpia, and pempek, siomay was influenced by Chinese Indonesian cuisine. However Chinese Indonesian siomay usually served not with peanut sauce, but in sweet-sour and spicy chili sauce instead, or with no sauce at all which resembles authentic Chinese shumai. Siomay has been incorporated into Indonesian cuisine for a long time, and the most famous variety is Siomay Bandung. It has been adapted into local Sundanese cuisine. Today, most of Siomay sellers are Sundanese. Another variety of siomay is called Batagor, also originated from Bandung. It is an abbreviation that stands for Bakso Tahu Goreng. Batagor is very similar to siomay, except that it is fried instead of steamed. Siomay is one of the favourite school meal for Indonesian students.
Varieties of steamed siomay to choose; tofu, potatoes, cabbages, bitter gourd and eggs.
