1. First of all, when handling shepherd's purse, wash it first, remove the old leaves and other possible dirt, and don't remove the roots.

2. Then, soak in light salt water for about 20 minutes. If you are too worried about being unclean, you can soak it properly, then rinse it with clear water and drain it for later use.

Finally, you need to blanch before frying shepherd's purse. After digging up the wild vegetables, everyone will clean them and fry them directly. Just like cooking, wild vegetables are different from ordinary vegetables, and shepherd's purse needs to be blanched before frying.

Although the shepherd's purse will lose some nutrients after blanching, it must be blanched for safety. Whether it is wild or planted shepherd's purse, blanching water can sterilize and remove some residual pesticides. Therefore, we must remind everyone here that when dealing with some unfamiliar wild vegetables, we should not only handle them carefully, but also have correct treatment methods. Only in this way can we ensure everyone's safety.
