Teach you how to cook braised trotters. How to make braised trotters delicious? Boil a pot of boiling water, add onion and ginger cooking wine, add pork legs, cook until the surface changes color, and pour out the water. Take out the pig leg and rinse it with cold water. In another clean cauldron, half of it is boiled with cold water, onion, ginger, soy sauce, old wine, sugar (or honey), vinegar and high fire, and then covered with low fire. When a pot of water becomes a spoonful of thick sauce, it can be served. Tip: 1. Sugar tastes better than honey, and honey seems to be healthier (pure psychological comfort, nutrition has been destroyed for so long). 2. Just keep the water bubbling with low fire when stewing, so that the finished product won't taste bad after 4 or 5 hours. 3. If you can't wait or don't like the soft skin, you can open the lid and stew for 2 hours before collecting the juice. Salt is the last seasoning, don't put it too early. The pot must be big enough, or the color will not look good.
