太平省
Bánh cáy is a variety of Vietnamese "bánh" (translates loosely as "cake" or "bread") made in the Thái Bình Province of northern Vietnam. It is made of sticky rice, sugar, gac or gardenia, sesame, carrots, mandarin orange peel, and lard. The mixture is roasted and ground, then put into a square box. It resembles the eggs of the "còn cây", a small crab in northern Vietnam which lives in rivers and rice paddies, from which this "bánh" derives its name. "Bánh cáy" is traditionally served with tea.
