Nasi dagang is a Terengganu and Kelantan breakfast legend, but it is a double coconut hit. The rice itself is steamed in santan, so it is already richer than plain rice at around 200 calories per 100g. Then it comes with gulai ikan tongkol, a coconut milk fish curry. Coconut rice plus coconut curry is why a plate lands around 830 calories with 32g of fat.
The official Malaysian food database actually puts the rice at 203 calories per 100g, so the rice anchor here is solid, not a guess. It is a delicious heavy breakfast. Eat it, enjoy it, just do not treat it as a light start to the day.
