1. First of all, you can soak beef in light salt water for a while before cooking, which will not only remove the fishy smell of beef, but also make it easier to cook.

2. Then, wrap a pinch of tea with gauze and cook it in a pot, which will not only increase the flavor of beef, but also make beef tender faster. It is emphasized here that never put tea directly into the pot, it is difficult to catch it.
