The history of rice in Taiwan
The white rice that Taiwanese consume today is a variety that was introduced and improved in the era of Japanese colonial rule: a short-grain “japonica” rice known as hōrai or penglai rice, with a slightly elastic mouthfeel and grains that tend to stick together. Before that, the staple food of the earliest Han Chinese to settle in Taiwan during the Ming and Qing dynasties was long-grain “indica” rice known as zailaimi, with a firmer texture. The culinary historian and writer Wang Hao-yi, who published the book Snack Institute, explains that zailaimi was introduced to Taiwan in the late Ming, some 290 years before the development of hōrai rice. “This means that the rice-based snacks that have come down to us from the Ming and Qing, including radish cake and savory rice pudding, were certainly made using long-grain rice.” In other words, says Wang, “There was no hōrai rice in traditional rice snacks.”
Wang states that as a result of the need for different textures, in some snacks newly harvested rice is used, while for others older rice that has been in storage for at least nine months must be used in order to get that elastic, chewy texture. Thus dishes like radish cake and steamed bawan must be made with old rice. It’s clear that a lot of knowledge and care go into such snacks.
For example, to make radish cake, one must use rice that has been in storage for at least a year, which is soaked in water and then ground into rice milk. Next the daikon radishes have to be peeled, shredded, and boiled in water to get rid of any off-odor. Then the shredded radish and rice milk are stirred together evenly and the mixture is poured into molds and steamed over a high heat for five to six hours. The amount of water in the rice milk, how long the radish is boiled, the ratio of rice to radish, and control of cooking time and temperature are all matters requiring special expertise.
How have this tradition and the associated skills been passed down for hundreds of years? Wang Hao-yi has pored over historical documents and tells the following bittersweet story:
At the end of the Ming Dynasty, when the Zheng family ruled in Taiwan, the last Zheng ruler, Zheng Keshuang, decided to surrender to the Qing Dynasty. When this news reached Zhu Shugui, the last claimant to the Ming throne, he decided to take his own life as a sign of his patriotism. Zhu owned a large stretch of farmland south of the Erren River in Tainan, and before his suicide he called together local farmers and bequeathed his land to them. After the Qing took over Taiwan, to express their gratitude for Zhu’s generosity local people prepared rice cakes that were used as religious offerings in the Zheng period, such as taro cake, brown sugar cake, and radish cake, and secretly went to Zhu’s grave to worship on his remembrance day, on his birthday, and at the Lunar New Year. The skill of making these cakes was passed down from generation to generation, until in the era of Japanese rule, when people no longer feared reprisals, they began to sell these snacks in markets, and the dishes spread across Taiwan to become part of everyday fare for the common man.
The fragrance and texture of aged long-grain rice in combination with just the right proportion of shredded daikon radish adds up to the appetizing flavor of radish cake that the food writer Wang Hao-yi calls “a gentle delicacy.”
