Bibim guksu or spicy mixed noodles is a popular dish, especially in the summer, as it needs neither many ingredients nor does it take a long time to prepare. The dish boosts the appetite, especially when people feel tired due to the hot weather. 

The dish has another name, goldongmyeon (골동면, 骨董麵), which means "straightening the bones." In the "Record of Seasonal Customs in the Eastern Kingdom" (Dongguk Sesigi, 동국세시기, 東國歲時記) (1849)there is a description of this dish. The book says, “A dish with buckwheat noodles, radish kimchi, cabbage kimchi and pork is called naengmyeon [cold noodles] whereas gongdongmyeon is a dish with potato starch noodles, pears, chestnuts, beef and pork.” According to this text, it can be assumed that both dishes must have been popular in the Joseon era. 

Bibim guksu was not only popular among commoners, but also at court. There's a description of the dish in "The Royal Protocols to Mark the 60th Birthday of Queen Hyegyeonggung Hong" (Wonhaeng-eulmyo-jeongrieuigwe, 원행을묘정리의궤, 園幸乙卯整理儀軌). It says that bibim guksu was simply “goldongmyeon with soy sauce seasoning.” Queen Hyegyeonggung Hong (혜경궁 홍씨, 惠慶宮 洪氏) (1735-1815) was the mother of the 22nd Joseon monarch, King Jeongjo (정조, 正祖) (1752-1800). 

Many people regard bibim guksu as a summer dish, but it's actually one of the seasonal dishes, along with red bean porridge, for Dongji, one of the 24 solar terms of the year that also marks the winter solstice. In the past, many people enjoyed naengmyeon and bibim guksu in the cold winters. People tried to "cure" the cold by eating cold food, just as they do the opposite in the summer by eating hot ginseng chicken soup (samgyetang, 삼계탕) during the three hottest days of summer, the Boknal days. 


Bibim guksu, or spicy mixed noodles, stimulates the appetite, especially in the summer, thanks to its unique taste that harmonizes beef, pork, mushrooms, vegetables and pepper paste. In the past, people enjoyed the dish not only in the summer but also in the winter.
