Throughout Indonesia, soto is known under various names such as the Makassar coto or the Pekalongan tauto. However, this traditional Indonesian soup is usually associated with the island of Java, where it is believed to have appeared in its original form.
Nowadays there is no right way to prepare soto because the varieties are numerous and usually adapted to local cuisines. Although it is believed that soto was developed because of a strong Chinese influence in the country, it is more likely that the soup was created following common cooking traditions of the area and utilizing the ingredients which were available in abundance.
This versatile dish also has a myriad of accompaniments such as stewed eggs, grilled offal, fried tofu, and either chili or soy sauce. Soto is regarded as comfort food, and it can be found everywhere in Indonesia - from local open-air eateries to high-end restaurants.
