Gejang, a beloved staple of South Korean cuisine, is a traditional dish that finds its roots in the coastal regions of Korea, where the bounty of the sea plays a crucial role in the culinary landscape. The dish embodies a unique and deeply satisfying flavor profile, being made from raw crabs that are marinated in a rich blend of soy sauce or spicy chile pepper sauce. This ancient method of preparation highlights both the freshness and natural sweetness of the crab. Gejang is often enjoyed with a bowl of steaming hot rice, allowing diners to savor the intricate layers of flavor that develop during the marination process.
Ingredients
