China

When visiting the graves of deceased relatives in China, tofu is customarily used as a food offering. The spirits of the deceased are said to have lost their chins and jaws for so long that only tofu is soft enough for them to consume. Tofu was generally exclusively marketed during the winter in China before refrigeration became available, because tofu did not spoil as easily in cold temperatures. Tofu spoils if left out for more than a day during the summertime.

Japan

Zen Buddhist monks brought tofu to Japan during the Nara period (late 8th century), originally named it “Chinese curd.” Following the Japanese invasions of Korea around 1592–1598, a Korean doctor and prisoner of war introduced a solid variety of tofu to Tosa Province, today’s Kochi Prefecture. Tofu was first used as a vegetarian substitute for meat and fish by Buddhist monks in East Asia, particularly those who practiced Zen Buddhism.

Tofu was first recorded in a Japanese text in 1183, when it was served as an offering at the Kasuga Shrine in Nara. Tofu Hyakuchin, published in 1782 during the Edo era, has 100 cooking tofu recipes. In Japan, deep fried tofu is known as atsuage or namaage.

Southeast Asia

Tofu was brought to Southeast Asia by Chinese immigrants from Fujian province, as illustrated by the fact that many countries in the region refer to tofu using the Min Nan Chinese pronunciations for soft and firm tofu, or “tu-h” and “tu-goan,” respectively. Tofu is widely available and utilized in many local recipes in Indonesia, the Philippines, Malaysia, Myanmar, Singapore, Thailand, Cambodia, and Vietnam.


Tofu Flavor

The taste of tofu is often bland, which is the taste that shoppers in North America prefer. In East Asia, a more beany flavor is liked. The beany or bland flavor is created during the grinding and heating process, and the flavor can be modified by using either a “hot grind” or a “cool grind.” By inactivating the lipoxygenase enzyme in the soy protein, which is known to cause off tastes, the hot grind process decreases the beany flavor. By removing these off qualities, the tofu becomes bland.

Extra Soft Tofu

Soy milk is fermented by combining it with seawater or saline water prepared with sea salt. The tofu curds stay loose and supple.

Soft Tofu

Silken tofu is another name for this type of tofu. This tofu is gypsum-gelled, undrained, and unpressed, with a high moisture content. To make silken tofu, coagulate soy milk without cutting the curd.

Firm Tofu

The pattern of the muslin used to drain this type of tofu is retained on the skin, and the outside is somewhat more resilient to damage than the inside. It is easily picked up with chopsticks.

Extra Firm Tofu

The extra firm type tofu known as Dòugān or su ji has had a considerable part of the liquid pressed out. Dòugān has the least moisture of all the fresh tofu varieties, the firmness of completely cooked meat, and has a rubbery texture. This tofu crumbles quickly when thinly sliced.
