The other day, I had a chance to have a cup of Omija tea from Korea. Omija is written in Chinese characters as "five-flavor compound" and looks like a cluster of red grapes. It is said to contain the five tastes of sweet, sour, bitter, spicy, and salty, and is so good for health and beauty that it has been used in Korean herbal medicine for centuries. And this Omija tea is a mysterious tea that changes its taste depending on the day's physical condition! The basic taste is sweet and sour, but it depends on which flavor you strongly feel...
