Hoi An Banh Dap

Hoi An bánh đập combines toasted crisp rice paper with a soft steamed rice sheet, pressed or cracked together at the table and eaten with a strong savoury dipping sauce.

Overview

Taste, technique, context and the way this food belongs to local life.

Bánh đập is a deceptively simple Hoi An snack: crisp toasted rice paper meets a soft steamed rice sheet, and the diner presses the layers together so the cracker breaks into bite-sized shards. The resulting combination is both brittle and supple. It is strongly associated with the Cam Nam riverside food tradition, where diners may pair it with stir-fried small clams and mắm nêm or another house dipping sauce. It is not the same dish as bánh sắn đập, which uses cassava; the Hoi An heritage office explicitly distinguishes the two.
