What is "rengginang"

Rengginang or ranginang is a kind of Indonesian thick rice cracker, 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. This cracker is quite different from other types of traditional Asian crackers such as the Indonesian krupuk and the Japanese senbei or beika; while most of traditional crackers' ingredients are ground into a fine paste, rengginang retains the shapes of its rice grains. It is similar to Japanese arare, and yet it differs because arare are individually separated larger rice pellets, while rengginang rice granules are stuck together in a flat-rounded shape. Rengginang traditionally made from dried leftover rice.
