2. Dry the eggs with paper towels so that no moisture remains.

3. Prepare a small jar with a sealing lid and pour in rice vinegar (just cover the eggs, it is best to use 9 degree rice vinegar).

4. Cover and seal for about 24 hours.

5. Open the lid after 24 hours. You will find that the egg has expanded like a balloon because the eggshell has softened.

6. Gently break the eggs with chopsticks. Be careful as they may spray into your eyes.

7. Stir the egg liquid and vinegar evenly together.

8. Replace the lid and seal for 24 hours.

9. When drinking, drink it with warm water, and you can add some honey to taste. The vinegar-egg liquid soaked in one egg should be used up in 7-10 days.
