Ssam

Ssam refers to dishes in Korean cuisine where some food is wrapped in other food. Often, ssam consists of meat such as pork wrapped in leafy vegetables. It is often accompanied by a condiment known as ssamjang and can also be topped with raw or cooked garlic, onion, green pepper, or a banchan (small side dish) such as kimchi. Ssam is usually bite-sized to prevent spilling out the fillings. Under the Buddhist influence that was especially strong during the Kingdom of Goryeo, killing and eating an animal was highly discouraged. This has led numerous Korean vegetable dishes, especially ssam, to be created and emerge as a prominent dish during the era. After its emergence, the dish was mentioned numerous times in the ancient Korean records. The ancient Korean book of customs Dongguksesigi noted that the women of Goryeo who were taken as servants by the Yuan dynasty made and ate ssam to have the taste of their home country's food and soothe homesickness. The same book also noted that ssam had become an established seasonal dish by the Joseon era, which was especially eaten as a festive dish during the day of Daeboreum. The ssam eaten during Daeboreum was believed to bring a good fortune and called bokssam (복쌈), which meant "fortune ssam".
