Ban xeo is a kind of crispy pancake which is one of the popular dishes in Vietnam, though sizes can vary; in Ho Chi Minh City, for example, the portion is comparatively smaller than those in Hanoi. Ideal as a snack, this savoury pancake is made using turmeric, coconut milk and rice flour; the fillings vary and can include shrimp, pork, bean sprouts, mushrooms and onions. One way to enjoy it is to wrap it in lettuce leaves along with herbs, basil and mint and dip it into a special fish sauce.
