I don't know how to, but Google gave me this as the first result and I think it's a little more detailed than RoadRipper's.
So...how to cook rice? like normal, what tipe of rice works best, what should I fill it with, It still don't explain much, but the bouth recepies are useful
I know a really good site that gives you detailed instructions. That site really helped me when I wanted to make rice balls last Christmas. We needed a couple batches for the party. Everyone there asked for the recipe afterward. It was a real winner!
