In that black "buah keluak" gravy drenching the rice are pieces of cow tongue which are decidedly chewy. Those black holey slices on the left of the plate are cow lungs, also known as "paru", which have a spongey texture. Understandably, this is the stuff of nightmares for some. But I lurrrrrvvve Nasi Rawon! A classic from Surabaya, East Java, it comes as a standard set with aforesaid cow organs, sambal cuttlefish, a small "begedil" (seasoned mashed potato ball), "tempeh" (fermented soya bean patty), "sambal belachan" and "serundeng" (dry-fried grated coconut). This came from "Sajisi Tradisi" located at unit #02-117 inside the Geylang Serai Market & Food Centre but you can easily find Nasi Rawon at quite a number of stalls.
