It must be soaked for several hours before being steamed and is sticky but dry when cooked. For eating, use the hands, serving as a sort of spoon to eat a salad or similar dish with. The flavour is quite subtle but goes wonderfully squidgy in the mouth.

You should be able to find the sweet rice in the ‘world food’ section of larger supermarkets.
