Zongzi (or zong) is a traditional Chinese food, made of glutinous rice stuffed with different fillings and wrapped in bamboo or reed leaves. They are cooked by steaming or boiling. They are known in Japanese as chimaki. Laotians, Thais, Cambodians (known as Nom Asom) also have similar traditional dishes influenced by zongzi. In the Western world, they are also known as rice dumplings or Chinese tamales.
Zongzi is traditionally eaten during the Dragon Boat Festival (Mandarin: Duanwu; Cantonese: Tuen Ng) which falls on the fifth day of the fifth month of the Chinese calendar (approximately early to mid-June), commemorating the death of Qu Yuan, a famous Chinese poet from the kingdom of Chu who lived during the Warring States period.
The shape of zongzi range from being relatively tetrahedral in southern Chinese cultures to more cylindrical in northern Chinese cultures. Wrapping a zongzi neatly is a skill which is passed down through families, as are the recipes. Like tamale-making in Mexico and Pamonha-making in Brazil, making zongzi was traditionally a family event with everyone helping out.
While traditional Chinese zongzi are wrapped in bamboo leaves, the leaves of lotus, maize, banana, canna, shell ginger or pandan leaves are sometimes used as substitutes in other countries. Each kind of leaf imparts its own unique smell and flavor to the rice.
The fillings used for zongzi vary from region to region, but the rice used is always glutinous rice (also called sticky or sweet rice). Depending on the region, the rice may be lightly precooked by stir-frying or soaked in water before using.
You can find authentic Thai Zongzi on many Thai Restaurants in Los Angeles.
