A new take on the age old rice ball is gaining popularity in Japan. Known as onigirazu, so named as chefs can quickly make them without worrying about getting sticky rice hands, these versatile and hearty dishes have rapidly become popular search subjects on cooking apps such as Cookpad and have even inspired several recipe books.

The photos above by Laura Tomàs Avellana on Flickr show how to make onigirazu in just a few steps. All that is needed is nori, rice, plastic wrap, and fillings.
