Tarakjuk is a variety of juk, or Korean porridge, made by boiling a mixture of milk and finely ground rice soaked in water. It is also called uyujuk, both terms meaning "milk porridge". The old Sino-Korean vocabulary, tarak derives from the Mongol word, taraq (torak). The history of tarakjuk dates back to the consumption of milk in Korean history. According to old records, the royal court of Korea began to consume milk since the fourth century, but milk cows were rare so milk was only available when a cow gave birth. Moreover, the freshness of milk was a vital factor, it could not be delivered from far places. Milk was considered a supplement food for special occasions, or recovery food after illness.
