The book Jasmine Toguchi, Mochi Queen is about a girl named Jasmine Toguchi who wants to roll mochi with her older sister, Sophie. There's one problem, though; you have to be 10 to roll mochi and Jasmine is only 8. Mochi is a gooey Japanese rice dessert. Jasmine decides to pound the rice for mochi instead. But with that, there's another problem: pounding mochi is traditionally reserved for boys, and the mochi hammer is heavier than it looks. Jasmine needs to turn her spaghetti noodle arms into strong arms for mochi pounding and convince her parents to let her pound mochi.
