recipe for the rice balls

I'm making the rice balls for a party tomorrow. It's very easy to make, so I don't think I need to write down how to make it....... Anyway, first, you prepare white rice (Japanese rice is better.) and something you want to put in the riceball. You boil the rise in a rice-cooker and then you roll the rice into a ball, putting things you prepared in the ball. You can wrap the ball with nori(laver) if you want to. That's all!!

Ingredients
---the rice
---something you want to eat
ex) tuna mayonnaise
broiled salmon
ume(Janpanese apricot)
