Tofu skin is commonly sold as dried leaves or sheets
Tofu skin is produced through the boiling of soy milk, in an open shallow pan, thus producing a film or skin composed primarily of a soy protein-lipid complex on the liquid surface. The films are collected and dried into yellowish sheets known as soy milk skin
The skin can also be bunched up to stick form and dried into something known as "tofu bamboo" , or myriad other forms
