Yujacha is a “tea” made from a marmalade-like syrup of yuja fruit and honey.
Yuja fruit is often misinterpreted as citron, but they are two separate fruits. Yuja is believed to be a hybrid of sour mandarin and ichang papeda. It has an uneven skin and resembles a small grapefruit in appearance.
Legend has it that Yuja was first brought to Korea by Jangbogo on a voyage from Tang China to the southern coast of Korea. According to the legend, the ship that carried Jangbogo was shipwrecked and the Yuja fruit in his jacket was crushed, releasing the seeds into the jacket. Supposedly during his travels in South Korea seeds dropped in many places and the Yuja flourished.
