Samgyetang (삼계탕)- Ginseng Chicken Soup is a warm soup for hot summer days. It is especially popular to eat this chicken soup on sambok (삼복) days, which are three distinct days of the lunar calendar—Chobok (초복), Jungbok (중복), and Malbok (말복)—commonly among the hottest and most sultry summer days in Korea. Eating samgyetang on these days is believed to promote health.
Some specialty restaurants in South Korea serve nothing but samgyetang, having gained local popularity through their special recipes for the dish, which are often kept as secrets. The dish is sometimes accompanied by a small complimentary bottle of insam-ju (ginseng wine) in certain restaurants.
