This is an improvised recipe that uses leftover rice.I made a few adjustments made after first having it, but by nature it is open for modifications and adjustments. If you are up to it, I think those will be amazing battered in a thin (tempura like) batter and deep/pan fried.   apx 340g cooked cooled short grain rice (about 2/3 cup, I think) that's how much I happened to have, no need to be accurate. Fresh rice can be used, but maybe under-cook it by a couple of minutes
