If you want to color walnuts with soy sauce, just soak them in soy sauce, but if you want walnuts to be colored well, you'd better play with them over time. We usually keep walnuts in a dry, cool and windless place after serving them, otherwise they may crack.
Wenwan walnut is something that many people like to play now. Now there is a method of coloring walnuts with soy sauce on the Internet. You only need to prepare a bowl of soy sauce, and then soak walnuts in soy sauce for a period of time.
However, this method of coloring walnuts is not recommended, because if you want to raise a really colored stationery walnut, you still need to accumulate a plate brush over time. This shortcut may do some harm to the walnut itself.
We must pay attention to the preservation method when we finish serving the stationery walnut. It is best to put it in a dry, cool and windless place, because the stationery walnut is easy to crack if it is placed in a high temperature and windy place.
