Was it a dessert or was it a side dish? Coconut rice with mango is a sweet in certain southeast Asian countries.
There is also sticky rice as an accompaniment and that will sometimes have chilies, lemongrass, kaffir lime leaves, ginger, lime, etc. A lot less palm or coconut sugar can sometimes be in there. Indian versions sometimes have actual shredded coconut.
My usual coconut rice is Dominican style, which is just pretty plain water, coconut milk, salt, oil, but delicious.
