The Yomiuri ShimbunThis series introduces everyday techniques to make bento lunches.
Onigiri rice balls are a staple of Japanese lunch boxes, but there are probably many people who feel bored with conventional fillings. To please the eye as well as the palate, why not try some unconventional ingredients?
It’s common to put things like umeboshi pickled plum or salmon in the center of a rice ball. The onigiri introduced below features rice mixed with several ingredients, so you can easily identify the flavor.
Satomi Sugiyama, manager of Tokyo Gas Co.’s Food communication Center, suggests making four kinds of atypical onigiri for bento lunches. “I recommend unusual fillings for onigiri to enjoy the unusual tastes,” she said.
Children might enjoy bento lunches with omuraisu (rice omelet) onigiri, as the paper-thin omelet and ketchup-flavored rice add color to the ensemble. After frying omuraisu ingredients with seasonings, mix them with rice and make rice balls. The onigiri is unlikely to harden as the rice is not fried, Sugiyama said.
Fried-cheese curry onigiri looks mouth-wateringly good, and the vivid purple color of red shiso and cheese onigiri will brighten up your bento box.
Your finished bento box will look even better if you mold rice balls into different shapes, such as circular, oval or cylindrical. In the gaps between onigiri, she recommends placing broccoli or mini tomatoes to add even more color.
Using plastic wrap to mold the rice balls is an important hygiene tip. After shaping onigiri, open the wrap to help the onigiri cool before putting them into a lunch box.
Avoid tightly molding the rice when you shape the onigiri, because it ruins the consistency.
“You just need to gently clench portions of rice three or four times to achieve the right firmness,” she added.
