There are varies ways to enjoy it, and the way generally depends on where you are, in china.
Northerners, or the people live near the coastal land used to boil it directly just like the way of boiling water.Then add some sugar and an (or more if you like) egg inside, no stir. Wait about 5 minutes, and enjoy it.
But my favor is to ice it, taste good in summer.
Climate in our city is desperate in summer, that temperature can keep peaking over 40 degrees Celsius, for half a month, at least.
