1. Ingredients: 8 lemons, 300 grams of rock sugar, and appropriate amount of water.

2. Prepare a few fresh lemons, soak them in water and rub the skins clean with salt.

3. Cut the lemon into slices on the chopping board. Prepare to be put together with rock sugar for later use.

4. Pour all the ingredients into the pot at once, and add a little more water. It doesn’t need to be too much, just enough to cover the lemon. Cook for about 1 and a half hours.

5. When the time is up, cook until thick and dark in color. After cooling, you can choose to store it in a sealed jar.
