; however, it does have a similar texture and flavor to some tofu products. Tofu skin's use was first documented in written records in China in the sixteenth century. It is widely used, fresh, fermented, or dried, in Chinese, Korean, and Japanese cuisine.


Early history

An early written reference to tofu skin appeared in 1587 in Japan in the ''Matsuya Hisamatsu chakai-ki'' hree-generation diary of the Matsuya's family's tea ceremonies The writer, Matsuya Hisamasa, states simply that tofu skin is the film that forms atop soymilk. Other written references to tofu skin appeared around that time in China in the ''Bencao Gangmu'' he great pharmacopoeiaby Li Shizhen. This work was completed in 1578, but not published until 1596. Chapter 25 states: A third known reference to tofu skin appears in 1695 in Japan in the ''Ben Chao Shi Jian'' (Wade–Giles: Pen Chao Shih Chien Mirror of Food in This Dynasty, 12 volumes This book was written by Hitomi Hitsudai in Japan, in Chinese. When Japanese read the Chinese characters for tofu skin, ''doufu-lao'', they pronounce them ''tōfu no uba. Lao'' or ''uba'' means "old woman" or "wet nurse".

. Because of its slightly rubbery texture, tofu skin is also manufactured in bunched, folded and wrapped forms, which are used as meat substitutes in vegetarian cuisine. Tofu skins can be wrapped and then folded against itself to make dòu baō ( zh, c=豆包, l=tofu package). These are often fried to form a firmer skin before being cooked further.


Forms

These are the three basic forms. Each comes in many varieties.


Fresh


Dried

Tofu skin may also be dried and sold as dried beancurd sticks ( zh, c=腐竹, p=fǔzhú, l=tofu bamboo). By layering or bunching fresh tofu skin or rehydrated tofu skin, then tying it tightly in cloth and stewing it, the dried beancurd sticks will retain their original shape. This bunched tofu skin is then called ''tofu chicken'' ( zh, t=豆雞, s=豆鸡, p=dòu jī, links=no; or zh, t=素雞, s=素鸡, p=sù jī, links=no). In Thai cooking it is referred to as ''fawng dtâo-hûu'' (, lit. foam tofu). It is commonly called foo chuk in Southeast Asia.


Meat alternatives

By layering and bunching the sheets in a certain manner, an imitation of chicken breast can be created with tofu skin. The effect is completed by frying the "skin" side of the tofu chicken until it is crispy. If stuffed with vegetables, it becomes ''tofu duck''. Likewise various other meat alternatives have been made in this way, especially by Buddhist vegetarian restaurants in areas of Chinese culture. The earliest process for making these meatless meats consisted of rolling thin sheets of doufupi, literally tofu skin, around a filling of minced, smoked, or other seasoned pieces of tofu skin, tying closed the bundle with string, and steaming until a meaty texture and flavor developed.


Log

Other methods include rolling the tofu skin tightly on a

and steaming it to form a log. When the log is sliced, each slice will be circular with a square hole in the center, which looks like old Chinese coins.
