How to Vacuum Seal Green Beans for Optimal Freshness and Longevity
To vacuum seal green beans, first wash and trim the ends of the beans. Blanch them in boiling water for 2-3 minutes, then transfer them into a bowl of ice water. Dry the beans completely and place them in a vacuum sealing bag. Use a vacuum sealer to remove the air from the bag and then seal it. Store the sealed bag in a cool place.
