Culinary delight from India's Bihar state

Litti chokha is one of the most popular street foods in India.

Litti are chargrilled flavour bombs, especially when freighted with chokha, the spicy stew of grilled aubergine, tomato and potato.

The BBC's Justin Rowlatt tastes this mouth-watering street food from the eastern Indian state of Bihar.
