What legume is the main ingredient in Korean bindae-tteok? Mung beans are the main ingredient in this Korean pancake.

Bindae-tteok is made by soaking and usually hulling mung beans, grinding them with water, and pan-frying the resulting batter. The batter is commonly combined with fillings such as mung-bean sprouts, bracken, kimchi, pork, scallions, garlic, and sesame oil.

The dish is also called nokdu-buchimgae, nokdu-jeon, or mung bean pancake. It is associated especially with Korean markets, including Seoul’s Gwangjang Market, where vendors fry it in generous amounts of oil. Its origin is linked to Korea’s northwestern regions, including Pyeongan and Hwanghae.

A common mix-up is confusing the mung-bean batter with the filling: ingredients such as pork, kimchi, and sprouts add flavor, but the pancake’s defining base is ground mung bean. The name tteok can also mislead English readers, since this version is pan-fried rather than a typical steamed or boiled rice cake.
