Preparation materials: no limit to fish scales, appropriate amount of garlic, appropriate amount of green onions, appropriate amount of vinegar, appropriate amount of soy sauce, a small amount of pepper oil, a small amount of pepper, a small amount of star anise, a small amount of white sugar

Production steps:

1. Place the fish scales in a pot under cold water, cook for about 5 minutes, and remove.

2. Keep cleaning and filtering the fish scales until they are relatively clean.

3. Put an appropriate amount of oil, pepper oil, garlic, and green onions into the pot and stir-fry until fragrant.

4. Then add the washed fish scales and stir-fry.

5. Add appropriate amount of soy sauce, vinegar, white sugar and water that has not covered the fish scales (do not add salt).

6. Add a little more pepper and star anise. Cover and cook for about 1 hour.
