The naming of a soto is pretty simple, usually we just append the location it hails from after soto. For example, soto Betawi comes from Betawi, which is Jakarta by the way :) Then, coto Makassar comes from Makassar, soto Bandung comes from Bandung, etc.
Soto ayam Ambengan is exactly like that, but I think it is way way WAY too specific since this soto actually comes from the city of Surabaya, from a soto restaurant located on Ambengan Street! I mean, if it is up to me, I would have called it soto Surabaya, less confusion. ;)
Now that you know how the soup got its name. I am going to tell you the characteristic of this soto.
Soto ayam Ambengan has a yellow colored soup since turmeric is one of must have spices to make the soup, and koya is always added when enjoying a bowl of this soup.
Koya is a powdery mixture made from crushed shrimp crackers (kerupuk udang) and fried garlic, good stuff I am telling you, it amps up the umami taste by a lot.
If you cannot find shrimp crackers, the best substitution would be crushed fried ebi (dried tiny shrimps).
Here is another shot with a broken down list on what goes into a soto ayam Ambengan, minus the soup by the way so you get a better idea. ♥
