Misu

Mișu is a beverage made from the traditional Korean grain powder misu-garu, which is a combination of 7–10 different grains. It is usually served on hot summer days to quench thirst or as an instant nutritious drink for breakfast or as a healthy snack.
In a Joseon Dynasty recipe book, misu was mentioned as stir-fried barley. Gu was a delicacy of that time and easy to serve as one went to travel.
Misu is made of glutinous rice and other ingredients, such as barley, yulmu, brown rice, black rice, black soybeans, corn, white beans, millet, and sesame seeds, which are ground, roasted and/or steamed, then mixed together. Misugaru is commonly added to water or milk and stirred to make a drink. Sugar or condensed milk can be added as a sweetener. The beverage is high in protein, vitamins, calcium, magnesium, molybdenum, folate, and selenium, and is a dieter's drink, as it is quite filling but low in calories.
