It’s all about the kind of rice you use and how you cook it @stacypro. You need a more glutinous rice like sushi rice and when it’s done cooking you need to give it a good stir to break it up a bit and really bring out the stickiness. The Feed Zone Portables book has lots of rice cake/ball recipes. I will see if I can find an actual recipe tonight for the tahini ones I like.
Since we are talking about rice balls, has anyone tried ohagi before? I love red beans so I am tempted to try making them sometime.
