Black Beans in Coconut Milk is a dessert that Thais enjoy year round, unlike seasonal desserts like mango sticky rice and durian sticky rice. Black Beans in Coconut Milk is versatile enough to have other ingredients added to make variations. If you have sticky rice left-over from mango sticky rice, add a spoon of the sweetened sticky rice to the dessert to get a new texture and flavor.
The black beans should be tender without the skin broken. The coconut milk sauce should be slightly purplish, not white and smooth without curds. You should be able to taste the palm sugar sweetness, which is distinct from cane sugar. The palm sugar is creamy and nutty.
