What it is

Boiling cane juice until supersaturated and letting it crystallise produced a solid sugar that could be stored and transported. The words 'sugar' and 'candy' derive from the Sanskrit sharkara/khanda.

Maurya-era texts already distinguish syrups and sugars (guda, khanda, sharkara), and the Greeks speak of 'honey from reeds' in 326 BCE; widespread crystallisation is usually placed in the Gupta period.
