Walk into any Japanese convenience store or supermarket, and you’ll find a row of rice balls waiting. You can always count on the old standards, such as salmon, pickled plum, and spicy cod roe being represented, but each store also sets aside a bit of shelf space for unique, limited-time versions as well.
In the past, this form of carbohydrate-packed one-upmanship has given us such wonders as the bacon cheeseburger musubi and headscratchers as the fish butt onigiri (musubi being one of the Japanese words for “rice ball,” and onigiri the other). It’s always a flip of the culinary coin whether these outside-the-box rice balls are going to be a hit or a miss, but when we heard about ramen-style onigiri, we were immediately onboard.
