Can I keep the brine I used to live in chicken feet for later use?

Yes, after the braised pork is fished out, boil the brine, let it cool and put it in the refrigerator. Cook it once every two or three days, and then put it in the refrigerator for a long time. If you don't want to use it for a long time, freeze it. Next time, you can use this salt water to marinate other meat. This is the legendary soup stock, hehe. Don't worry, no problem.
