Glutinous rice (Oryza sativa var. glutinosa or Oryza glutinosa; also called sticky rice, sweet rice, waxy rice, botan rice, biroin chal, mochi rice, and pearl rice) is a type of short-grained Asian rice that is especially sticky when cooked. It is called glutinous in the sense of being glue-like or sticky and not in the sense of containing gluten; on the other hand, it is called sticky but should not be confused with the other varieties of Asian rice that become sticky to one degree or another when cooked.
