Out of all the different iterations of sticky rice wrapped in some type of leaf, whether it’s lotus leaf or banana leaf, perhaps my favorite sweet version is Vietnamese sticky rice with banana wrapped in banana leaf. The sweetness of the sticky rice plays well with the coconut milk that it is cooked in. This infusion of coconut flavor into the rice combined with banana creates a great flavor profile that can be found in a few other types of banh and che: most notably for me is banh chuoi nuong (Vietnamese banana bread).
Another thing that I love about banana sticky rice is the fragrance. The banana leaves give off a great leafy aroma and the sticky rice is fairly fragrant, almost akin to basmati rice. Not only do the leaves give off a grant fragrance, but their leafiness is also imbued into the rice itself.
To prepare the banana sticky rice, the rice must be soaked for at least a couple hours (overnight even) before cooking. I’m not really sure why it needs to be soaked, but if I had to take a guess it’s probably because the rice is steamed rather than boiled. Soaking the rice before steaming may give the rice the proper moisture it needs to soften when cooked.
