Soak the bought lemons in salt water for 15 minutes (some lemons will have a layer of wax on their surfaces, so soaking in vinegar is not good for your health, so you can remove all lemons with salt water), then wash the cans and dry them for later use. Be careful not to touch water or oil.
Take out the soaked lemon and cut it into thin slices. The exact number of lemons depends on the size of your jar. Pay attention to dry the water on the knife and chopping board when cutting.
Put the sliced lemon slices one layer of lemon and one layer of rock sugar in a sealed jar.
Then pour in 9 degree white vinegar, cover the jar and seal it. You can eat the crystal sugar when it melts.
How to eat: drink two slices of lemon and three spoonfuls of vinegar with water at a time. It may taste a little sour. You can add some rock sugar appropriately, but it is best not to add it.
It is best to eat after meals, because it has the function of cleaning the intestines. Unlimited times, drink if you want.
The above is the correct way to add vinegar to lemon slices. Of course, if you still want to achieve the effect of beauty, you can use honey instead of rock sugar, which can not only achieve the same sweetness, but also have the effect of nourishing yin and beauty. But after all, this is only a dietotherapy aid, not a real staple food, so ladies who love beauty should not use lemon vinegar as a real staple food. Excessive absorption of citric acid is very harmful to the stomach, so it must not be eaten as a dinner.
