Xoi Vi La Cam
available at Viet Wah grocery, $1.95
I think that one of the most relevant measures of human ingenuity is the number of delicious ways in which we as a species manage to combine beans and rice. To that long list add xoi vi la cam, a Vietnamese sweet sandwich (and close cousin of xoi nep than).
A thin, crumbly layer of sweetened mung beans is held in place by chewy slabs of sticky black rice, which turns an intense violet color when cooked. Because of its pigmentation, black rice is up for membership in the fabled "superfood" club--but more importantly, it has a rich, nutty flavor that brings out the soft sweetness of the beans. A sprinkle of toasted sesame seeds on the surface adds crunch and more nuttiness.
