How long can water chestnut be kept dry in the refrigerator? Generally, raw water chestnuts are dirty after they are picked, and farmers' uncles will wash them and sell them in the market.

So if we want to put it in the refrigerator, we'd better dry it and keep it dry.
Generally, it is best to eat the water chestnut bought back as soon as possible. If it is raw, there will be a lot of water on it.
