Street food batagor which costs 0.4 USD is very cheap

In general, batagor is made from softened tofu and filled with a mixture made from mackerel fish and tapioca flour then shaped like a ball which is fried in oil for several minutes until cooked. Another variation is dumplings, fried and served with batagor and combined with peanut sauce, sweet soy sauce, chili sauce and lime juice as a complement.[3]
