Soto is the name for rice soup, found all over Java. Lamongan is a town not far from Surabaya and soto Lamongan is its speciality. This dish is available all over Surabaya, and I tried it at a streetside foodstall near my hotel.
The rice is in a turmeric yellow stock, with white noodle, chicken, egg and a squirt of lime juice. It tasted richer than the Central Javanese soto I am used to, but less curryish than the Jakartan soto I have tried. It was delicious, rich and filling but not too much so, and is well worth a try if you get the opportunity.
