1. Clean the fresh pepper after picking and drain the water.

2. Divide into sealed bags according to each dosage, add appropriate amount of cold boiled water, and then seal.

3. Place in the refrigerator to freeze. When eating, take it out and soak it in tap water for a while. The ice inside and the bag will be easily separated. When making soup, take out the whole piece and put the ice and Sichuan peppercorns into the pot together.

4. The green peppercorns preserved in this way retain their original flavor and will not change color or taste even after being stored for one year, just like freshly picked green peppercorns.
