1. Rinse ginger with clear water and put it in a ventilated and cool place. Let it air dry for about 3 days, as long as the skin of ginger looks a little wrinkled.

2. Put the dried Guizijiang into a fresh-keeping box or a sealed glass bottle for sealed preservation.

3. Pour sweet noodle sauce, soy sauce, sugar, oil consumption and other seasonings into cinnamon sauce, stir well, and finally pour pepper water.

4. Cover and wait for Guizijiang to marinate 10 days before eating. Of course, if you pursue the taste, you can marinate for a few more days, and the flavor is better.
