One of the greatest challenges with watercress is preserving it; we work hard to ensure it is as fresh as the day we harvested it when you take it home to your family. Thanks to a vacuum cooling system, we are able to prolong the shelf life of our watercress; however, if watercress is not handled correctly, the shelf life can be reduced greatly.
When you bring your watercress home, immediately place it in the crisper of your refrigerator. Heat is not the best friend of watercress, keeping the watercress cold will maintain the freshness.
We usually recommend wrapping the watercress in a damp paper towel and storing it in plastic bag or air tight container.
Before serving, bring the watercress back to life in an ice bath for 15-30 minutes. When we vacuum chill the watercress, excess water is removed to quickly cool the watercress and prolong its life, but with a quick and easy ice bath the watercress will be rejuvenated. Always give your watercress an extra rinse for the last cleaning.
We often take watercress with us when we travel as omiyage (gifts for friends and family--and yes, you are allowed to travel outside Hawai'i with watercress!). We have been known to revive our 2 week+ old watercress with an ice bath in the refrigerator overnight.
All parts of our watercress are nutritious and delicious. Do not feel the urge to chop and throw away the stems! We actually prefer them for the fresh crunch only Sumida Farm watercress can provide. We hope you enjoy your Sumida Farm watercress and let us know how you keep your watercress fresh at home!
