Bindae

Bindae-tteok , or mung bean pancake, is a type of buchimgae (Korean pancake) that originated in the Pyongan Province. It is made by grinding soaked mung beans, adding vegetables and meat and pan-frying it into a round, flat shape. Bindae-tteok first appears under the name binja (빈쟈) in the Guidebook of Homemade Food and Drinks, a 1670 cookbook written by Jang Gye-hyang. The word appears to be derived from bingjya (빙쟈), the Middle Korean transcription of the hanja word 餠𩜼, whose first character is pronounced bǐng and means "round and flat pancake-like food". The pronunciation and the meaning of the second letter are unknown. Tteok (떡) means a steamed, boiled, or pan-fried cake; usually a rice cake but in this case a pancake. During the Joseon era (1392–1897), richer households would dispense bindae-tteok to poorer people gathered outside the South Great Gate of Seoul during times of hardship.
