preference

My late dad's preference for the glutionous rice balls ( tung yuen) is the savoury type. I developed a craving for them this year. I have been making the sweet version last time.
Besides a sign of being older when one eats the tung yuen, the chinese also use it to test whether the married couple will get a son or a daughter. I am not sure how it is done but this takes place on the eve of the wedding. Probably see which colour balls rise to the surface first in the boiling water?
Which kind of balls do you prefer? sweet or savoury?
