One of the Japanese ingredients that’s hard to identify without explanation is Yuba, also known as soy milk skin. As the name suggests, when soy milk is gently heated, a thin film forms on the surface where it meets the air. This delicate film is lifted with bamboo sticks to create yuba.
The Japanese word “湯葉” literally means “hot water leaf,” with “湯” meaning “boil” and “葉” meaning “leaf,” describing its thin, leaf-like texture.
When eaten fresh with wasabi soy sauce or used in dishes, it’s called Nama Yuba (fresh yuba). When dried, it becomes Kansō Yuba (dried yuba), which comes in various forms such as flat sheets (Hira Yuba), knotted yuba (Musubi Yuba), and rolled yuba (Maki Yuba).
