Without wafers, you can't make it because hard ice cream, after all, like popsicles, melts when it's preheated. The wafers are made of glutinous rice flour and are preheated for a long period of time to prevent the oil from touching the hard ice cream so that it doesn't melt. You can get them at the market. If you can't, I'll buy them for you. I don't know where you are, but I'm in Beijing
