Mung bean cake is a sweet food made of fine mung bean powder with sugar, and vegetable oil or animal fat, usually lard. The cake is cut into small cubes, wrapped in foil, then put into little boxes or wrapped in greaseproof paper and put into bars. The cake is often used when drinking green tea because it will create a sense of relaxation. The local area famous for mung bean cake is Hai Duong.
The ingredients for making these cakes include mung beans, sugar, lard, essential oil of pomelo flowers. All must be selected and purely processed. The four ingredients above have to blend together in the right proportion because if you exceed that ratio, the cake will have poor quality. Wrapping paper and the color of the label must be carefully considered so that the cake will last longer and enhance the beauty of the cake.
