The puffed rice cake is a flat hard food made with puffed rice. Typically, it is eaten as a healthy snack or used as a base for other ingredients.
Some rice cakes are flavored. Common flavorings include chicken, sweet chili, cheese, butter, chocolate, caramel, salt and vinegar, or apple cinnamon.
Rice cakes are often made into sandwiches, especially when used by dieters as a substitute for higher-calorie bread.
Most rice cakes are round, though square varieties are available. Some manufacturers make mini rice cakes, marketed for snacking.

Wor Bar
Traditionally, Wor Bar (Guoba in Mandarin, translates to "pot's burnt") refers to the slightly browned rice that is stuck to the bottom of clay pots, which, after caramelization, results in the rice being formed into a single piece and giving it a slightly burned flavor. It may be brewed into tea, or served as part of a main meal by pouring savory meat sauces over the heated puffed rice cake.
