Preparation materials: 1 dried pomelo peel, 200 grams of sugar and appropriate amount of water.

1. Prepare the required materials, as shown in the following figure:

2. Scrape the grapefruit skin with a kitchen scraper, scrape it as thin as possible, and don't take the white part out.

3. Pour grapefruit peel, proper amount of sugar and water into a small pot. After the fire boils, cook for about half an hour.

4. Cook until the grapefruit skin is almost transparent, as shown in the figure, and collect the juice on high fire.

5. When the soup is almost collected, take out the boiled transparent grapefruit peel and spread it on the drying net to cool. The surface of the boiled grapefruit skin is slightly sticky and tastes like peony skin when chewed.

6. Pour a proper amount of sugar into a lunch box or a small pot with a cover, pour the grapefruit skin into it, cover it and shake it to make it stick to the grapefruit skin evenly.

7. Finally, put the finished grapefruit peel sugar into a sealed jar and store it in cold storage. Just take it out when you want to eat.
