Japanese tamago refers to a type of sweet, fluffy omelet commonly found in Japanese cuisine. It is made by whisking eggs with a bit of sugar, soy sauce, and mirin, then cooking the mixture in a rectangular pan. The eggs are layered and folded multiple times to create a light, airy texture. Tamago is often served as a topping for sushi, particularly in sushi restaurants, where it is known as tamago nigiri. It can also be enjoyed on its own or as part of a bento box. This dish showcases the delicate flavors and techniques characteristic of Japanese cooking.
