1. Cut a pair of lemons.
2. Use a juicer to squeeze out the juice.
3. Strain it with gauze.
4. Place the filtered clean lemon juice in a bowl and set aside.
5. Prepare a stainless steel pot or ceramic pot (do not use iron or aluminum pots), pour water into it, turn off the heat after boiling on high heat, and pour the sugar into the pot.
6. Stir a little with chopsticks to mix the sugar and water, then heat on medium heat and cook until the sugar is completely melted. Please do not stir again during this process.
7. After the syrup is boiled, pour in fresh lemon juice. After it is boiled again, turn to low heat and simmer slowly. From this time until the syrup is cooked, remember not to stir the syrup again.
8. At this time, a part of the sugar water may stick to the pot wall. In order to prevent this part of the sugar from producing sugar crystal particles, you can take a brush dipped in water and brush it around the pot wall. When the water flows down the pot wall, the sugar on the pot wall can be washed into the pot.
9. After cooking the syrup, turn off the heat.
10. After the syrup has cooled down, find a sealed jar, put the syrup in it, and use it after 1 day.
