Oil and Lacquer

To make xoi gac (momordica sweet rice) you take gao nep, which is a sweet and sticky rice, and mix it with gac fruit, which is momordica fruit.  Then, cook the rice and fruit for about an hour.  Meanwhile, cook up some dau xanh, which is mung bean.  When the dau xanh is ready, smush it until it turns into a paste.  After an hour, the rice will be ready, and it will be flavored and dyed by the fruit.  Flavor it some more with sugar.  Then, find a mold, oil it up, and compress about 1/3 of the rice into it.  After, compress another 1/3 with mung bean, and then the final 1/3 with rice.  Take your rice cake out of the mold.  Sprinkle sesame seeds on top.  Done.
