How to make corn juice:

1. Peel the corn and remove the whiskers, wash and peel off the corn kernels. As shown in the picture, it is easier to cut it directly with a knife

2. Put the corn kernels into the pot, add an appropriate amount of mineral water, and then cook over low heat until the corn kernels are completely cooked. Skim off the scum on the surface;

3. Pour the cooked corn together with the soup into a blender and crush it. If you sift it through the flour, the taste will be better;

4. Finally, add Sanhua evaporated milk and sugar. If there is no evaporated milk, add 1 bag of milk. In addition, by poking two holes on the top of the evaporated milk, this "opening" method can be easier to store than the traditional method, but it still needs to be used up as soon as possible after opening.
