Don't wash. Wash it when you eat it. If you eat it in a day or two, this method is simple and practical. Many times, we will not eat all the mulberry seeds at once, and we will always leave some more or less, but it is a pity to throw them away. At this time, if we want to store mulberry seeds, we can choose to wash them with salt and sugar, and then store them in a closed container, which can last for about half a month.
