Ikoko is a confectionary with a filling of brown sugar and red bean paste, accented with the fragrance of ginger, wrapped in an outer layer made from flour, etc., then baked in the oven. Their feature is that they are not entirely filled with red bean paste in the middle but have an air pocket which creates a unique taste sensation. The flavor is a simple one from the good old days, and you will sense the nostalgia as you eat one. Great with a cup of green tea, ikoko is a common favorite amongst tea connoisseurs. Ikoko is said to have begun being made in the Kaei Period (1848 - 1854) and had the reputation of being a confectionary with high nutritional value since the Tang dynasty of China.
