Bombay duck

Harpadon nehereus, commonly known as the Bombay duck or bummalo, is a species of lizardfish. Adults may reach a maximum length of 40 cm , but the usual size is around 25 cm (10 in). The small bomelon fish caught in Bombay (now Mumbai) was traditionally coated in asafoetida and dried in the sun, becoming pungent with a strong salty taste. Fried and crumbled, the fish preparation called Bombay duck became a popular condiment in Anglo-Indian cookery.
