2. Wash cowpeas from beginning to end.

3. Dry the washed cowpea and put it in the sun for one day (to prevent the cowpea from softening during the curing process).

4, take the right amount of water to add edible salt, add as much salt as possible, less salt will not only lead to bean souring, but also easily lead to bean deterioration and rot.

5. Put the beans in the salt water. If the beans are pickled in a jar, put pebbles on them. The heavier the beans, the better. If they are preserved in relatively small bottles, try filling them with corks.

6. Put the jar or bottle in a cool place, and the beans will be marinated in a week.
