I tried another product of Chinatown which is the Glutinous Rice Balls with peanut and white sesame filling since I liked the chewiness of their mochi balls. It was also good! I have tried so many brands already, and this is the one i liked best.
To make the soup, just boil water and sugar together. I suggest not to make the soup too sweet because the filling of the balls is also sweet already.
Happy Chinese New Year!
