A Soybean Sojourn: Tofu-Making In Guangxi, China - Part 1
Thursday, September 14, 2017 | Posted By Karen Axelrod in Factory Tours
Tofu (soybean curd) is a food of Chinese origin that occurs widely in the cuisines of East Asia. Tofu is cultivated by coagulating soybean milk and then pressing the resulting curds into soft white blocks. Because it is a good source of vegetable protein, tofu has become popular throughout the world, especially among vegetarians. During a three-week trip to China, we had the opportunity not only to learn how to make tofu but also to participate in making it.
In Yangshuo, a town and county in southern China’s Guangxi region, our driver and guide took us to a small local farm owned by a family named Qin.
In the courtyard behind the farm’s clay-brick adobe, we ground soybeans that had been soaking in water for two hours. Using a ladle, we poured a spoonful of soybeans and water into the center of the stone mill and turned the handle counterclockwise.
After considerable physical exertion, we were rewarded by seeing white frothy soybean milk emerge from the bottom of the circular gray stone mill and drop into the metal bucket below.
Next, the owner of the house showed us a more automated way to grind the soybeans. A small machine ground the beans, and he combined the two batches together in a red bucket. Then he and his wife tied four corners of fabric onto opposite ends of a wooden cross to create a sieve. Next, he poured the mixture into the sieve. His wife, Li Qin, occasionally dropped boiling water over the mixture. Then he swirled the fabric sieve around. Our daughter Hilary helped him rotate it.
White liquid filtered out into a bucket below. After adding gelatin, he let it set for 10 minutes. Then he draped the cloth over a shallow square wooden box.
With a red plastic pot, he ladled the resulting mixture into the cloth-covered wooden bin. Then he folded the cloth over the mixture, placed the square wooden lip on top, and pressed it down with two bricks. He let it sit and firm up for a while. Next he removed the wooden lid and flipped the box over so that the tofu wrapped in fabric was released from the mold. He gingerly pulled the fabric away from the tofu. However, it did not separate easily, so he brought it over to the well. He placed the tofu in a shallow red bucket and pumped cold water into the bucket so that the cold water could ease the separation. With patience and perseverance, and a little help from Hilary, he managed to separate the fabric. Then he cut the soft, fluffy tofu into small rectangles. His wife stir-fried it in a steaming wok heated by burning wood. They cooked us a delicious meal to share.
For the mass production of tofu, a much more automated system is used. In fact, most Chinese people buy tofu at their local market rather than from a farm. They cut off a desired rectangular slab and carry it home in a small, clear plastic bag.
