Banh Beo (Hue Steamed Rice Cakes with Shrimp and Scallion Oil)
Little dishes of rice flour and tapioca batter go into the steamer and come out as soft discs, translucent at the rim and opaque white in the middle. This snack from Hue in central Vietnam is topped with dry, crumbly shrimp, toasted in a dry pan until every bit of moisture is gone; any left behind turns soggy on the cake.
