1. Clean the fresh bracken, dry it completely, put it in a fresh-keeping bag and put it in a dry and cool place or put it in the refrigerator for refrigeration.

2. Pinch the head and tail of the fresh bracken, drain the water, put it in a basin, add salt, and marinate for about half an hour. Put the marinated bracken in the jar again, cover it, and it can basically be preserved for one year.

3. It is suggested that fresh bracken should be fried now, so that the value of bracken can be brought into play.
