Different countries have different types of rice dumplings. In Taiwan, the regional differences are quite distinct. As a wrapper, the north uses Makino bamboo leaves and the south uses sweet bamboo. Hakka people on the island use neither and opt for the fragrant leaves of a plant called alpinia zerumbet, or shell ginger.
