Teriyaki is a popular Japanese cooking technique that involves grilling or broiling meat, fish, or vegetables that have been marinated in a sweet soy sauce mixture. The marinade typically includes ingredients like soy sauce, sake, mirin, and sugar, which create a glossy, flavorful glaze when cooked. This method is often used for dishes like teriyaki chicken or teriyaki salmon, and it can be served with rice and vegetables. Teriyaki has gained popularity worldwide, leading to various adaptations and fusion dishes that incorporate the sweet and savory flavors characteristic of this traditional Japanese cuisine.
