Mung bean cake (lvdougao) is a traditional and popular Chinese dessert in summer. The main ingredient, mung beans or sometimes called as green mung bean is a common and daily ingredient in Chinese cooking. In traditional Chinese medicine, those little green beans have a cold property, which can further help to protect our body from hot temperature in summer.Personally, I love various recipes made with mung beans or related ingredients. For example, in Sichuan province, there is famous Liangfen made with Mung bean starch. And there is a national glass noodle—mung bean noodles. I have made two versions this time. One batch of the cakes are custard yellow while the other batch is matcha green( reproduce the green color of the cake).
Many varieties of mung bean cake are available in China from taste, from color to shape. But in general, they are shaped by different cake moulds like mooncake moulds. For a smoother and fine taste, it is important to use unshelled green beans. Unshelled green beans are easy to find in baking ingredient store in China. You may try to search it in Asian stores, sometimes they are named as yellow mung beans (spilt mung beans). Another option is to pre-soak the green mung beans and peel by hand. But it is a really hard task requires patience and time. I have tried one time and do not recommend you doing this.
Pre-soak the yellow mung beans overnight. Rinse and dry.
In a high pressure cooker, add clean water to slightly cover (3-4 cm higher) the beans and cook for a bean (or meat) procedure until the mung beans are easy to smash.
Then smash the mung bean until fine and smooth. It is quite easy when they are well cooked.
Transfer the mung bean into a pan, add butter and vegetable oil and keep frying over medium slow fire.
Add sugar when the oil is well absorbed.
Continue frying over slow fire until the mixture can be easily shaped into a paste. Divide the mixture into two equal portions and transfer one portion out.
Add around 5-8g matcha powder for coloring.
Transfer the mixture into a strainer and then press with a spatula. You may ask help in this step or consider this as a way of body exercise. This will give your mung bean cake a super smooth taste.
And then divide the mixture into small portions around 30g-40g. If you want them to share similar size, use a kitchen scale to weight each portion or resort to a scoop. I wrap some of them with 10g red bean paste. But this step is optional.
Then shape it with a mooncake mould. I am using this one :New Moon Cake Decoration Mold mould 50g & flowers Round 4 stamps DIY Tool. For tips about how to use this tool, you can check the video in snow skin mooncakes.
All the mung bean cakes need to be kept in small air-tight packages after cool down completely. They can be kept for around 1 week.
