What it is

Sugar-making reached the Ryukyu kingdom in the early 1600s, brought back from Fujian by an official, and it became the islands' tribute crop. Only eight Okinawan islands still make the real thing — whole cane juice boiled down and set in blocks with nothing removed, which is where the salt-mineral edge comes from.

In the kitchen

The lumps will not dissolve on their own — smash them in a bag or grate them before they go into a batter, or the crumb comes out gravelly. A block dropped into a pork braise gives colour and salt at once.
