Gangjeong (강정) is a hangwa (한과, traditional Korean confection) made with glutinous rice flour. It is a deep-fried "rice puff" with hollow inside, coated with honey followed by nutty beans, nuts, seeds, pollen, or spice powders. Gangjeong is often served during important events such as weddings, ancestral rites, and Korean New Year celebrations. Yugwa was widely distributed after the Goryeo Dynasty due to the influence of Buddhism, and was called "Goryeo disease" in the Yuan Dynasty of China.
