When Vietnamese go to Vietnam, they go with a food list to check off. On the top of my list was Banh Beo, like my grandmother (Ba Noi, in Vietnamese) used to make. It is a common dish of Hue, my father's hometown in central Vietnam.
The steamed rice cake is topped with finely chopped shrimp, scallions and/or fried shallots.
Steamed and served in tiny bowls. Drench with a dipping sauce of fish sauce and rice vinegar. Spoon up. Pile the bowls. Eat to your heart's content.
