Imagine warm, hand-shaped triangles of rice sprinkled or filled with salted salmon or Japanese pickled vegetables that are wrapped in roasted nori. These are onigiri or, as they are also called, omusubi. They're popular, easy-to-make Japanese snacks that Sonoko Sakai says are convenience store darlings and every mom's answer to bento-style sushi. In her new book Rice Craft, Sakai gives step-by-step instructions for how to make them at home. Find a recipe for her bacon and scrambled egg onigiri on the Good Food blog.
