Tamago, or Japanese egg, is a popular ingredient in Japanese cuisine. It is often used in dishes like sushi, where it is prepared as a sweet, layered omelet called Tamago sushi. The egg is typically seasoned with sugar, soy sauce, and mirin, giving it a unique flavor. In addition to sushi, Tamago can be enjoyed on its own or as part of a bento box. It is rich in protein and can be cooked in various styles, including rolled or folded. This versatile ingredient is a staple in many Japanese meals and is loved for its delicate taste and texture.
