Nasi tumpeng is a unique Indonesian dish with a distinctive presentation - a cone of rice in the middle with a variety of side dishes arranged around its base and served on a round tray. No utensils, nasi tumpeng is best enjoyed by hand.
The dish has deep spiritual roots and significance. In my opinion, it is the most Indonesian dish - not due to its pervasiveness as it is mostly found in Java, but because it has been around for the longest time in Indonesian history.
(Indonesia's Tourism Ministry in 2014, named nasi tumpeng a national dish along with soto, rendang, satay, nasi goreng, and gado-gado.)
