Onigiri

I've been doing some experimenting recently making おにぎり (Onigiri) aka, "rice balls".  I've been taking it very literally as being a ball and have not added any Nori wrapping yet.  I've been just sticking with variations of tuna and mayo that I read about online.  It's a pretty simple and easy dish to make, and I end up with enough for 2-3 meals from one batch, which is nice.  Cook a cup (uncooked) or rice int he rice maker, dump it in a bowl with a can or two of tuna, spoon some mayo in, add whatever flavoring I want…
