The method of making brown sugar ginger water is as follows:

1. Slice the old ginger, add the old ginger to the pot with cold water, and simmer slowly.

2. When the ginger water turns a little yellow, add brown sugar. Add a few pieces of brown sugar. If you like it sweet, you can add a few more pieces.

3. Brown sugar is added to reduce the spiciness of ginger and make it taste better.

4. After this, you are done. Drink a cup of brown sugar ginger water in the winter morning and you will feel particularly warm.
