Rice is not a product that you need to malt, I dont even think you could malt it if you really wanted to. Maybe some sort of hippie style organic wild rice, but not the stuff you would use to brew. For brewing your just going to rely on the enzymes that are in your barley to convert the starches in the rice. You will have to do a "cereal" mash, and no, it doesnt involve any lucky charms! just google it on here and you'll find plenty about them.
