Glutinous rice (Oryza sativa var. glutinosa; also called sticky rice, sweet rice or waxy rice) is a type of rice grown mainly in Southeast and East Asia, which has opaque grains, very low amylose content, and is especially sticky when cooked. It is called glutinous (< Latin glutinosus) in the sense of being glue-like or sticky, and not in the sense of containing gluten. While often called "sticky rice", it differs from non-glutinous strains of japonica rice which also become sticky to some degree when cooked. There are numerous cultivars of glutinous rice, which include japonica, indica, and tropical japonica strains.
