Puffed rice and popped rice (or pop rice), are types of puffed grain made from rice commonly eaten in the traditional cuisines of Southeast Asia, East Asia, and South Asia. It has also been produced commercially in the West since 1904 and is popular in breakfast cereals and other snack foods.
Traditional methods to puff or pop rice include frying in oil or salt. Western commercial puffed rice is usually made by heating rice kernels under high pressure in the presence of steam, though the method of manufacture varies widely. They are either eaten as loose grains or made into puffed rice cakes.
