1. Ingredients list: 500g hawthorn; 500g rock sugar; 1000g white rice vinegar.

2. After buying hawthorn, wash it with water and dry it. If you are in a hurry, you can directly soak it in white rice vinegar and clean it without drying it.

3. Remove the stems from both ends of the hawthorn, and make five cuts along the outside. This way the hawthorn can be soaked in hawthorn vinegar faster.

4. Weigh 500 grams of old rock sugar and set aside. If you buy large pieces, you can heat them in the microwave for one to two minutes. Take them out and gently tap them with a hammer or kitchen knife to break them into pieces for easy soaking.

5. Get a clean and waterless container, put the hawthorn first and then the rock sugar. Finally, pour the white rice vinegar in and tighten the lid. As long as the rock sugar melts, you can drink. The longer the hawthorn is soaked, the better the taste. If you don’t like sourness, you can drink it with water. Drink 25 grams of hawthorn vinegar on an empty stomach in the morning and evening. Do not drink fruit vinegar on an empty stomach.
