How to preserve fresh wild bracken for a long time

1, wet storage. Preserve dishes by salting. The head and roots of bracken should be cut off or pinched off, washed and drained. Put the cleaned bracken into the pot, pour in the edible salt, the ratio of bracken to salt is 7:3, stir the salt and bracken evenly, and marinate for 30-40 minutes until the bracken is drained and the color becomes heavy. Prepare a vegetable jar, put the pickled bracken in it, cover it tightly, and seal the mouth with clear water. The shelf life of bracken is extended to about half a year.

2, vacuum preservation. Fresh bracken is stored in vacuum, and the food in vacuum state is not easy to deteriorate. Put the bracken into a sealed fresh-keeping bag, and evacuate the air in the bag to keep the bracken fresh and not rot for 3 to 5 months. Vacuum-packed Pteridium aquilinum can be preserved for a longer period of time.
