Rengginang or ranginang is a variety of Indonesian thick rice crackers, made from cooked glutinous sticky rice and seasoned with spices, made into a flat and rounded shape, and then sun-dried.

The sun-dried rengginang is deep-fried with ample cooking oil to produce a crispy rice cracker.

The most common rengginang are deep fried with added pinches of salt for a traditional salty taste.

Other variants have other ingredients added to enrich the taste, such as dried prawn, terasi (shrimp paste), or lorjuk (razor clam).

After it is separated from the cooking vessel, the stuck rice is sun-dried until it loses all of its liquid contents.
