First batch I made on April 10, 2011 for the very first time and they did not last long, along with my work friend we ate them in less than 5 days. On April 15, 2011, my second batch of rice cake turned out even better and bigger; I used up the left-over sweet red-beans filling from the first batch; and coated them with Mugwort and Roasted Soy Bean Powder. These four are for my friends and the rest are for ourselves, hope they last longer than a week! ;) They are deliciously addictive.
The recipe is here.
