1, go to the supermarket to buy a fresh lemon, glossy best.

2, go home, dry it with paper towels (it is best to rinse it with water first), put it in the refrigerator for two hours, the time is not too long or too short, it is difficult to cut for a long time.

3. Use a cutting knife to cut the lemons on a clean fruit board, then cut the lemons into 15 to 20 slices. This should be a quick process, and then place it in a covered tupperware container.

4. Put it in the freezer of your refrigerator. When you need to use it, cool it with boiling water or directly with mineral (pure) water, etc. It is recommended that you use half a cup of water per cup. If you use a kettle, you can put in one or two pieces.

5. You can add honey or rock sugar to flavor it.

6, do not use too hot water to soak, which will lose the lemon's flavor and nutritional value. In summer and fall, this method can make you drink half a month of delicious lemonade.
