Yakgwa is a Korean traditional dish. It is made mainly from honey, sesame oil, and wheat flour. Literally, yakgwa means the medicinal (藥) confectionery (菓). This name came from the main ingredients it is made of. In Korea, during the Joseon Dynasty era, honey was considered as a medicine good for health.
The origin of yakgwa is not clear since this food had many different names. However, it seems like Korean people started to eat it during the Unified Shilla era. During the Goryeo Dynasty, yakgwa was known even in China under the name Goryeo mandu. This is from the Joseon Dynasty era that yakgwa was being called yakgwa. (Photo Source)
