Ingredients: Zhimeizhai sweet vinegar 3-5kg (you can add it later if it is not enough), sugar 1 piece, ginger 2kg, eggs 10, and half a pig's trotters. First, put 3 kilograms of sweet vinegar in the casserole, then simmer over high heat. No water can be added in this process. Second, after peeling and washing ginger, pat it loose with the back of a knife and dry it. Then stir-fry the excess water with low heat. Add some salt when frying. After drying, put ginger in a sweet and sour earthenware pot, add a little salt and a proper amount of sugar, and cook for at least one hour. Turn it on and cook slowly. Sweet vinegar must cover ginger. If it is too sweet, add sweet vinegar; if it is too sour, add sugar. Cooking will become more and more difficult. The amount of sugar tablets can be added slowly, because the more ginger vinegar is cooked, the more delicious it is. The amount of sugar tablets should be added in several times, not too much at a time, but the time for cooking ginger vinegar should be divided into several times. Leave it overnight after cooking and cook it slowly the next day. After many times, ginger vinegar will be delicious. Third, after a night, the eggs are cooked and shelled, put into a sweet and sour casserole and simmer for 20 minutes, and turn off the fire for one night. Fourth, after two nights, you can eat trotters and buy fresh trotters, but ginger vinegar must cover the ingredients, so that it is easy to taste. It is best not to buy materials hidden in the snow. After the pig's feet are singed and washed, cut into pieces, fly up, pick up the supercooled river, remove the fishy smell and dry the water. Put it in ginger vinegar that has been boiled all night, it will be easy to taste. In fact, you can add pig's feet when adding ginger slices, but according to experience, such pig's feet are easy to produce oil, which will make ginger vinegar too greasy. There are a few tips: 1. Open the lid of the cooked ginger vinegar to prevent moisture from mixing. Don't cover the pot of ginger vinegar until it freezes to the left. Remember, this is very important! 2, ginger vinegar will be more delicious, and the materials can be continuously enriched, add ginger vinegar.

Besides, you can eat it after cooking, but it is not necessarily the best. You should wait in a cool place for a while to make sure that vinegar covers ginger, pig's trotters, etc. In about three days, it will get better and better. However, when eating ginger vinegar, you should cook it again, which is more delicious!
